Can't detect any USB device

[Alexei]

Hello

I have a Windows XP Pro SP2 installed on my PC. I had a printer and an external modem connected through USB ports. They were working fine until 2 days ago they stopped working. My PC can't detect anymore any USB device. I checked that USB is enabled in BIOS. I even reinstalled Windows XP but still can't detetct USB devices.

I run out of solutions, so please does anyone know what's going on?

Thx you

Do you have other USB devices to test out? Did you install any new hardware/software at the time this failure started occuring? How are the devices connected, i.e. are they each on their own USB port or are they on a USB hub?

Hi CptMurphy

Thx for this quick reply

I tried to connect a scanner but it still undetected.

The devices are connetced directly to the PC with no hubs. And I didn't install any new software or hardware.

I used system restore first then reinstalled windows but nothing can help.

So you've tried known working devices and they don't work? It may be that your USB ports are fried. Have you tried to plug in these devices while in safe mode? One at a time? Also, are you pluging them directly into the back USB ports? Or on the front? If it's in the front, check the cables that go from the mobo to the front I/O panel. If it still doesn't work than it looks like you'll need to get a new mobo, unless another member has a better suggestion.
