I have just put together a new pc and I'm having some problems with the USB. I have enabled the usb in the bios and windows XP is detecting the ports. When I plug in a device though XP acts like nothings changed. The devices I've tryed are an HP 970and a SanDisk Card reader. I checked the websites of both products and followed their instructions but still nothing. I decided to hook up the front USB connection on the case to the motherboard and windows detected that properly as well. When I plug the devices into those USB ports they both work fine. So it appears to just be the USB ports on the motherboard. Again, the bios does say they are enabled and XP does detect them. It just doesn't do anything when something is plugged into them.

It may be that there's another jumper on the systemboard in order to connect both front (ie jumpered) USB devices and the ones in back. You may have to move a jumper to enable both front & back USB.

Which Systemboard (make/model) did you purchase?

Some USB ports may also require a patch for USB 2.0 devices to operate properly with the systemboard (or at all)... so look on the motherboard manufacturer's site for USB updates/patches and make sure you have the latest available drivers for your board.

In addition to Anna's answer, check the device manager Universal Serial Bus Controller. If there is a yellow Question mark by it, you'll have to load the USB drivers for the mainboard. they are usually on the driver disk you got with the mainboard.

note: to get to the device manager, click start, go to settings, control panel. Click on the System Icon. Click on the hardware tab, then device manager tab. Down at the bottom of the list you should see Universal Serial Bus Controllers. Expand it in the left pane. Any yellow exclamation marks for USB means drivers haven't been installed and need to be installed.

Turned Out that the connector on the front and back are USB 2.0. The devices say they are supported on 2.0 ports but once I ran a connector from the 1.0 on the motherboard and plugged the devices in, it worked like a charm.
Thanks for answering though!
