"I had a generic USB hub on a Windows 2000 SP4 machine that worked. After a blue screen STOP: boot failure problem was repaired. USB is OK, but The hub won't work.

These drivers didn't help."

  3. Click the Update Driver button and follow the instructions.

In most cases, you will need to reboot your computer in order for the driver update to take effect.
