No USB devices detected in XP

By Red Dragoon ·
I just built a brand new system for my client and clean-installed XP Home. USB support is enabled in the BIOS. In the Device Manager, USB support/hub entries are there. When I connect any USB device (mouse, ethernet, card reader) to either port, nothing happens. I have also run the Add Hardware Wizard, but it's like it's not even attached. The power light on the card reader comes on.

A motherboard (M/B) these days comes with more than two built in USB ports. Some USB ports must be connected to the motherboard (e.g. front side USB ports that are built in to the case).

Try the following steps if applicable. At the end of each step, try your USB mouse, printer, and so on. Stop if the problem got resolved.

1. Install Service pack 1 if not done already ? use Microsoft driver whenever possible.

2. Install the M/B driver ? there may be patch available.

3. Disconnect the card reader if it is internal ? the reader caused conflict.

4. Do BIOS flash to the latest one ? go to the M/B manufacturer?s website and see if the latest one addresses the issue.

5. Replace the M/B ? you got a bad M/B.

2.5 Disconnet all USB cables - may have to rewire or to swap case if front side SUB.

I removed the cables for the front usb ports from the motherboard, and after that plugging the devices into the rear worked.
