View Full Version : Help! winxp usb problems...

14-11-2007, 07:19 AM
I've been running into really strange problems with my usb ports... nothing i plug in works, I've tried plugging in several keyboards, jump drives, pen tablets, etc and the comp doesn't even recognize that something has been plugged in. First I thought it was just some bug and I updated my drivers but alas no solution. The weirdest thing is that I can plug in my usb mouse and it works fine!

Can't even boot entirely because the only keyboard(s) I have is usb...

If SP1 or 2 is installed, delete the USB controllers entry in device manager and reboot.

If theyre not installed, install one of them.

Thanks I'll try that out but any suggestions as to how I'm supposed to get into windows? Can't really get too far without a keyboard... haha

Its xp service pack 2 by the way.

can you get into the bios, some pcs need usb keyboards to be enabled in there

Try this one - it has worked before! Unplug the power cord from the PC and leave it overnight then retry in the morning.

Have you tried all USB ports? Whats the brand/model of the mobo

Did u build it, or buy it as a system?

Cant be the drivers, if it doesnt work, outside of windows.

Whats USB 2 on, in the BIOS?? Normal or Hi-speed?

Use a PS2 keyboard (buy beg or steal one)
If you have USB ports on the front of the PC, unplug THAT cable.

I built it myself, has an asus p5n-e sli mobo installed.

Well fortunately we have progress! The keyboard posts and all seems to run fine until I get to the welcome screen of windows, and then the keyboard stops responding. I looked through the bios and the only usb option I have is to enable/disable the controller. I'm afraid to disable it because with them disabled I have no keyboard.

Edit: The funny thing is that the only usb ports that seem to respond to anything are the ones in the front. The onboard ones don't do anything. I'm living in a dorm in college so finding a ps2 keyboard has so far been impossible, but I guess I don't have another choice.

Did u install EVERYTHING in the way of drivers??

Try safe mode, can you get into that?

As Steve said, try a PS/2 kb.

Youre not using a Razer copperhead USB mouse are you? Whatever this is.

It looks like if the latest version of the BIOS isnt installed this mouse can freeze the system.

You're not the only one with this prob (http://vip.asus.com/forum/view.aspx?id=20071112060252828&board_id=1&model=P5N-E+SLI&page=1&SLanguage=en-us)

Safe mode.
Delete them.

Anyone happen to know another way to get into safe mode? When I press F8 for the boot menu there isn't an option, my mobo manual is no help whatsoever.

Press F8 again. After u select the boot disk.

Hold it down. The other pc here has the same thing (F8 for the boot disk and safe mode).

14-11-2007, 09:25 AM
Safe mode didn't help, still can't type in my pass at the login screen. >.<

You'll have to find or buy a PS/2 kb then. If you're still using the USB kb.

14-11-2007, 12:32 PM
Looks like thats the only thing I can do. Finding ones gonna be a quest in itself, but you gotta do what you gotta do right? haha

thanks everyone!

hi the prob u are experiecing could be the fact that win xp sometimes turns on the power management for usb root hub

go to device manager right click usb root hub then power managment disable power management this now means the usb will remain active

hope this helps :thumbs:

Well, he would if could log into windows, to do it.

We had this exact problem on 1 of our girls PC's the other day

After heaps of searching on the internet I found a solution that worked for us

1. Shut down Windows
2. Unplug the PC from the wall
3. Switch the on/off switch a couple of times
4. Plug i the PC and start up the machine

I suspect it was because an Ipod was removed from the PC whilst syncing either way the fix worked immediately

Good Luck
