I have an ABit KT7A mb, just recently the USB ports failed to recognize any hardware. Power is working out the port, but it seems that no serial traffic is running back and forth.

What I have done:
Upgraded bios
added Abit's USB patch
unplugged usb cables, reattached.
changed from ACPI to standard mode
checked bios settings as per abit recommendations.

Any help would be greatly appreciated.

BTW, the chipset is VIA. I have read that VIA usb and microsoft code has a problem relating with each other. maybe I just put a NEC chipset USB side card in. But I would like to know if anybody else has had this problem and fixed it and how!

I don't know about Abit boards but the MSI K7T 266 Pro version 1.0 [VIA chipset] had a problem with the onboard ports. It was a chipset problem with no fix [ MSI came out with a version 2.0 board which solved the problem]. The only way to get USB ports on this board was to buy a USB PCI card.

Paul's VIA and A-Bit related FAQs are fairly thorough, and have helped me get past a number of issues.

While I have not had the USB problem, I do recommend that you try my favorite universalsocket A fix.
Manually set the CPU FSB and clock multiplier in BIOS settings.
For some reason, many socket A motherboards under-clock the CPU. I have seen a number of "strange" problems corrected by manually setting the clock speed.
