I have the same board and it has caused some problems. I bought an X800XT graphics card From Simply Computers, which proved to be fauty, Simply were taken over by Misco and I had to wait a week before customers base records were transferred from Sipmly to Misco before I could even start to get a 'Retuns Advice' Five weeks on, after newmerous e-mails and promises I am still waiting for my card to be 'repaired' by Misco. a company to avoid.

I could not use my USB ports on my P4C800-E to get pictures from my camera. I googled and found this. Thanks for posting it. My situation is a bit odd though. The USB port I use for my mx500 mouse (if you are looking at the back of the PC, I use the first one) and it has always worked. But I try anything else, gamepad, camera, etc and the damn thing never works. ):

Exactly. My Microsoft Intellimouse Explorer USB mouse has worked from day one. Has anything else? No. No other devices will operate other than my mouse, and I have been struggling all night with my Sidewinder Force Feedback 2 and I cannot get it to work. A waste of money.

Microsoft reported the problem as being "some ASUS model motherboards have an ohm 47 resistor at R232 that reduce the USB power supply to inadequate levels."

yea, this just happened on my p4p800 SE, i'm gonna call asus tech support and see if they can help, maybe i can rma it. if i find anything i'll post back

Same problem here with p4p800 SE in a Mesh Computer. Their advice requested. Total USB failure after disconnecting a PDA cradle. Device Manager believes USB ports all functioning but no equipment connected. Will post again when I know Mesh's views.

Wow, there seems to be an epidemic. I plugged in my Zen Micro mp3 player and >zot< ... OS froze. On reboot, I noticed that my mouse wasn't working. I swapped it into all of the other USB ports, then slipped on a PS/2 port converter and it lit right up. All ports are dead. I've uninstalled and reinstalled to no effect. Misery loves company.

This seems to be the definitive thread on the topic:

Same issue with
ASUS P4C800-E. Plugged in PDA cradle, computer froze. Reboot - all USB ports dead. Added a PCI USB card for $19. Seems to solve the problem instead of buying new motherboard.

Almost same issue... My Razer Boomslang usb mouse works fine, but all other usb ports are dead. Very weird... Every now and then the usb ports work, but it's very random, and I'm never sure what I've done (if anything) to get them to work...

Re earlier post, machine has needed a replacement motherboard. Don't waste time with BIOS/software reconfiguration if you have the same problem!

I have a p4p800 SE and all of a sudden no usb ports are working? This sucks read through threads probably same issues as above.

I've had the same prob with my P4C800-E Deluxe and i found a way to solve it (at least for me)

All i did was a PSU-Reset so just pull out the power cable , then press the power button on your computer case for like 10 secs and then plug the power cable back in and reboot. Worked for me, hope it does for you.

Same problem here with a P4P800SE. Been having it since last year and I though it was my "special" copy of Win XP :)

USB mouse and keyboard works, but everything else is intermittent--depends on device. I'm sure this is related to the power drain that the MSFT article talks about. Kind of disappointing that I'm getting this off of my first Asus board. I've always used Abit in the past.

OMG. Ok I thought that my Sidewinder Precision 2 joystick was having the issue for the past 3 months. So what I did was took a knife and sliced apart the usb connector and then after no avail chucked the whole joystick in the garbage. And now today, when I get an xbox 360 controller and it doesn't work, I discover that it was my mobo the whole time! I am so mad.

Same problem, dead USB ports, both front & back. My board is an ASUS P4C800-E deluxe. bought it in 2004, now it's gone!

My Asus motherboard's USB ports all went dead about two months ago. I clean reinstalled Windows XP home and updated all drivers which did nothing to help. I'm sick and tired of damn electronic equipment which doesn't work properly.

Seems all are in the same boat. Mine is p4p800 VM series. My HP 1010 Laserjet worked fine. Installed a USB Bluetooth dongle. Now dongle works. Printer maybe once a day. On plugging USB device not functioning. I am sick & tired.

same shit here too.....p4800e deluxe....all usb went dead....thought id stick with asus again....big friggen mistake...got p4s800d-x and usb headers on main board pooched on my month later....screw asus if they gettin my business again especially with new boards having to install sata drivers with a dam floppy disk when installing windows....its just madening

I have a asus P5ad2 premium MB. I've bought it 14 months ago. Since 2 months all USB ports front and back are dead. I've tried biosupgrade, clean install. Nothing works.

I have p5ad2-e premium. My USB ports are dead. However I don't know if it is due to my Antec Neo 480w Power Supply going up in smoke for no reason. (hate that smell) I dont know what that would have to do with the USB but when i replaced the power supply all my USB ports are dead. Bios initilizes USB on boot ok. In the bios doesnt reconize any devices. In device manager says everything is fine. no ports work front or back. peace

Well, I've just joined the club. I have a ASUS 4S533-E and I'm dead in the water. Same issues. Dead for every new thing plugged in, but the printer and mouse work without issue. Talk about a cluster frick. I'll tell you what, my first call is to the people who built this to give them a piece of my mind. This little event has taken a day off my work. Bummer.

The rear USB Ports on my MSI Board are on the fritz.
They work, but can stop responding for a few secs (causing my mouse to lag). A few times the ports would completely stop working, and windows would report a device being uninstalled.
Occasionally unplugging my mouse and reinserting it would fix (temporarily).

My 2 front USB ports seem to work fine though. I have my Razer Diamondback plugged into that now. Very odd.

M using asus p4c800-e mother board from last 6 monts my usb was working gud but from my last format my usb ports r not working i update the drivers n reinstall the window 5 times but noting works now m buged

Well I just suffered the same problem. My computer crashed and then I restarted my computer then poof all USB are not working. I reflashed BIOS and everything and nothing works.

I have a slightly different problem. It says that one of the USB devices attached to the motherboard has malfunctioned, and Windows does not recognize it, but everything is working perfectly fine. I would just ignore it except it keeps on telling me...

same issue here. p4p800 se. recently all usb decided to stop functioning. everything else is fine. I have tried all methods mentioned above. everything shows fine in device manager. oh well, maybe it's time to go to c2d

Reassuring in a way to know others having problems. My Mesh computer has ceased to have any working USBs. It's under warranty, so tech advice said reload drivers. This doesn't work still. It's going to go back for repair. What a waste of time!

My P4P800SE just bit the USB dust, and I find that I am also looking at a new MB.

Wow! Same problem here but with 2 different motherboards. MSI 955X Platinum and MSI 975 Platinum. At first the 955X's USB ports died (used it for around 2 months). Got it replaced with a 975. Worked fine for aroud 6 months. Plugged in my USB printer today. And voila! All USB devices stopped working. Plugging anything in now produces that "device has malfunctioned" error. How nice!

Same happened to my motherboard P4P800-VM. All USB drives gone. I got three years out of them - a little consolation.

Same thing with a P4P800VM, all USB ports dead. Dear club members, would you please advise me a reliable MB manufacturer ?!

Hi Everyone!
I feel better now knowing that I'm not the only one with this problem. My motherboard is a P4P800MX, and yesterday the USBs bit the dust, thought it was software and spent the day trying to fix it. Deep down in my gut I knew it was the motherboard, found this site, and just confirmed that. What the scary thing is that my last MB, an ASUS, lost it's USBs 3 years ago, and I bought this one to fix it........shame on me! I did notice that my machine had been slowing down an locking up a bit, I don't know if it was related,

Just checked another website, and it seems that the blame is being placed on the Intel ICH5 chipset, and it's failures are from static electricity discharge. True, it is winter, heat is on, and there is much static around, but......... I still have my old P4S533MX which suffered the same fate, but has an SIS962L chipset. The ptoblem is probably still ASUSs since it appears to only happen on their boards, but I'll look into it further.

Same problem, so frustrating, it started trying to connect a busbi memory stick, it would not load. Yet my sons worked fine on our computer. Now my mouse wont work and can not reinstall, plus tried to plug my camera in today but that has failed me too. I could through the thing through the window. I am not about to contact Dell help line - see if they can inlighten me.

ok now that we all have a problem with the dayum p4p800 se how do we fix it? bios upgrade what what??

I have a P4C800 E Deluxe. all USB ports went dead front and back last week. wrote zeros to drive, clean install and nothing, decided to go to asus website and update bios. Big fucking mistake, now the system won't boot, and when it does it hangs. I can't just get into windows to revert to old bios because i can't ever make it there. Called customer service and some lame excuse for a tech support tells me i have to have a floppy drive to revert to old bios! I don't have a floppy! and neither does anyone else in the year 2000, seriously who uses that shit! Asus will never get another dime from me. I'm going to google their website and click on it every fucking day just so google charges them or yahoo for that matter!!

I have had the same issue with the Asus P5NSLI boards. One lost USB after five months, the other not quite two months. Incidentally, Asus is highly regarded and I have (until this issue) not had problems with nearly 50 Asus motherboards over the years I've been doing system builds.

Asus boards are overrated shit! For a company so highly regarded for their motherboards there is an awful lot of customer complaints, because their board rated so highly in internet reviews, then when all the real motherboards hit the market (not the review motherboards they send to reviewers) customers realise they were duped into buying an overrated piece of shite motherboard! Type Asus and shit into any search engine and see what comes up! Reviewers also need to be held responsible for their actions too by testing motherboards bought from a supplier not boards they are sent specially from the Manufacturer! Guaranteed after this post some Asus Fanboy will post a comment raving on how good Asus boards are and they have never had a problem with Asus and Asus boards made them want to be a better person(LOL), but the fact is there are alot more problems with Asus boards than there should be for such a trusted name! So open your eyes and ears people and ask the man down at your local computer shop what he recommends, he should know he's the guy that puts them together every day! Basically what I'm trying to say is don't just trust a brand name or a review site for your next motherboard purchase, go ask the guys down at your local computer shop what they recommend, after all they build computers for a living!

Got the same problem both front and back side USB ports on my P4P800SE after 2 years of usage. I bought an usb PCI card, working fine. I wonder if there is a performance decrease due to motherboard USB problem?

Same thing on my Asus A8N SLI Premium.

Won't be buying Asus next time!

I tried P4C800E USBs and all failed. I tried with P5W DH Delux USBs and some passed. I put a new USB card on P4C800E and some of it's ports are working. When I put a powered USB hub on P4C800E delux. System becomes unstable. Do I need to change the Brand of MB?

I have the same problem. Mouse used to freeze now and then, but since plugging in a Logitech quickcam, the USB port has died. Printer was sharing the same port, so now I cannot print.

Hoping the solution is linked here somewhere!

Have a geForce 6100-M7 with all USP ports dead. Did a clean install on spare drive to no avail. Downloaded mobo drivers from Biostar site since Nvidia dumped this mobo, not on their site. Definitely hardware. Not sure what caused it, happened gradually, first two didn't work then the rest failed two at time. USB is so great, now the greedy scum has figured how to make it prematurely self-destruct.

I have a P5NSLI and all USB ports dead front and back after 2 weeks...I will call Asus and see if they can replace it.

I have the PC4800-E motherboard and all USB ports failed over the weekend. My 3 year warranty just expired (of course), so I just put in a USB PCI card and I'm back up and running. Since I will probably replace the board in the next year or so, this was the cheapest route to statisfaction.

p4p800 se, same problem, all usb ports are dead. tired of search

The same problem here... I have P4P800 SE and all 8 USB ports are not working... Voltage it pass throught the usb because me flash disk's is lighting when i connect it but the PC does not react... I try reinstalling windows but nothing happens!!!

My Usb ports on Asus p4p800se suddenly has stopped working after used usb memory, have tried reinstall everything drivers bios ....

Install a usb PCI card in
an empty slot.
Remember to disable the motherboard usb in set up.
Then Install new drivers.

It's not just ASUS. I've got a four year old ABIT MB that just did the USB dying thing. We traded a bunch of machines around in my family (so and so needed the ram, so and so didn't need xp, etc). Of course, I inherited the one that was "running fine until I touched it". Now, all USB ports dead. I am inclined to blame the Powersupply, as the machine had been giving it's previous user those weird random issues that hint of power problems to come. Swapped the MB to a new case/new PS, but still no USB. Will take the advice and get PCI USB card, then swap this machine with yet someone else. (my kid couldn't care less if it's got USB as long as it gets to the internet - gotta game!)

Same Deal, P4P800-E with 4 back, 4 front USB2 ports, Only 2,4,5 and 8 work. Pity is I need three at the back, so a PCI card it will have to be.

And another one. The USB ports on my P4C800 Deluxe come off and on, without any particular reason. Sometimes they work, sometimes they don't, without me changing anything. It's the ghost in the machine, I think.

This problem just happened to me as well. All front USB ports are now dead. An Hp a1250n. I believe the mobo is from MSI. It's still under extended warranty. Will see what they do to repair it...

P4S800D-X.

wow! I wonder Why all of my USB Devices have Malfunctioned at the same time! lolz!

2 Kingston Flash Drives, BT Dongle, Printer, Camera, Mobile etc etc! :@

It was my first Asus.. and i think it might be my Last.. Ever heard of an Intel MB failure? Except for the legendary D865GBF which led me to this board!! :@

My MB is still in Warranty but I don't think they might help me in getting me a replacement board since they don't do Socket478 anymore! :S

my m2nnpv-vm asus mother board lost its usb ports after working for 25 days.

asus is overrated. this is a huge mess for me. i will probably buy a pci usb card instead of going through reinstalling windows which is often the case when you switch out a motherboard. the os is directly connected to the motherboard and needs to be reloaded in most cases.

My older Mesh (4-5 years) has started to lose its USB ports. The trigger was an attempt to set up a link with a Sony Ericsson camera. I thought it was the camera but the PC is now losing contact with flash cards (that previously worked), printers at the end of long cable runs and other items but some other devices work. I am going to install a powered USB hub (then there is only one USB socket to feed) and see if that works. And a clean install while I am at it. The machine has not had a registry clean since new.

I have a p4c800e-delux and also had a problem with a usb port. But not a port on the motherboard but on a usb2 pci card. But my problem was letting my stepson use the computer as he tried to put a usb microphone the wrong way round and it sounded like my computer fried. After reboot the computer it would not even get to post but if i had the sound on you could here that anoying voice that asus provide but you can't understand. So can someone tell me if that is it for my board and if it would have affected any other parts that plug into the board?

I have an ASUS A8N SLI Premium MB and just now not quite a year old my two front USBs 'died' Still under warranty but has ASUS corrected the problem?????

Well, today it happened to me. I've got an ASUS P4C800-E Deluxe, and after connecting a Fuji FinePix A800 USB-camera the system froze. The USB ports were gone after rebooting the system. That's it. I've had it with ASUS. I've been having problems with the new ASUS P5B-Plus Vista Edition mainboard, today I lost my USB ports on the P4C800-E Deluxe and I am not going to buy another mainboard from ASUS.

That worked for me too, try it:

All i did was a PSU-Reset so just pull out the power cable , then press the power button on your computer case for like 10 secs and then plug the power cable back in and reboot.

Yep, the same damn thing seems to have happened to me and my Abit Abit IP35-E. Had a Samsung D900i transfering pictures when all of a sudden BONG! all 4 of my usb's died at once.

So that's a cold booting issue and now 4 dead usb's. Great work Abit.

Hmm, makes me wonder if it realy is the static electricity. I plugged an irda port into the integrated backpanel USB of my P4P800SE. I had a lot of driver problems and had to reinstall a number of times. It sometimes worked, sometimes it made a hard system reset during the regular windows driver search. After the last try the motherboard failed to go on with the boot sequence and hanged at the asus intro screen. It was only capable of carrying on after I removed the irda port. Now everytime that socket is occupied, it fails to boot and fails to operate that USB device, but otherwise it's functioning normally. Funny...

Wow, the PSU reset worked. We are back in business and everything's functioning again. Thanks!

I downloaded the ASUS S3 USB registry updated which had no effect whatsoever.
The PSU re-set did the trick though.
Excellent find!

CHECK THIS OUT !!!!
I have a P4C800-E, tried a SanDisk Cruzer 2G thumbdrive, the report was it could not find the unit...same as all the above issues everyone has been having....BUT I plugged a BELKIN Express Hub (7 USB Expander) into the 'SAME' usb socket and it recognized the expander and anything I plug into it now works fine....????
Note...the expander comes with an external 5V power supply...but I do not have it plugged in, so it is using the mother boards +5V drive for the USB port....
not sure what this means..but the USB ports that I thought were DEAD are NOT....I suspect it may have something to do with the loading of the USB+ / USB- lines, where now the Belking HUB is taking up the slack....
Hope this helps...
Chuck

Same problem on an IBM 8307NWG mobo. No power on neither front/rear USB connectors.
I reset BIOS values to factory defaults and they are alive again :-)

The PSU reset worked for me too. Thank god for this forum. I'm back up and running again.

Wow after 4 years now I know what the actual problem is. My ports would intermitently work and actually stopped working after I plugged in an external HD. Sometimes my joystick and printer would stop as well. Live and learn!

Old ASUS A7N8X Deluxe; USBs all died on power supply change. The PSU reset described here worked for me.

Adding to this with 6 dead USB ports on an ASUS M2NPV-MX ... and only 2 PCI slots so the card option is out. I hope ASUS staff are reading this thread!

This happened to my Asus P4P800 SE last year. All of a suddent the USB ports stopped working.

I put in a PCI USB card to get round the problem.

The latest problem is that it won't let me into the BIOS, so I have got no sound now, after the last time I re-installed XP.
