Hello WinDrivers.com, ((( A bit long, but detailed for help )))

As I've read many other posts, but I still cannot resolve this problem.

I have a Asus A7V333 with 2 USB1.x and 2 USB 2.0 on-board ports. It also has two more USB ports that can be setup for USB 1.x or 2.0.

My problem: My USB 1.x ports will work, however my USB 2.0 will not work. They will not respond when I attach any USB 2.0 device to them such as my FireLite 60GB Ex HDD I got. I seem to be getting power cause I attach a small flash memory stick and I get a steady light. I went through my device manager and there is no USB 2.0 controller shown or even one missing a driver (e.g. Unknown Device). There are two 'USB Hub Roots' and two 'VIA Rev 5 or later USB Universal Host Controllers' the USB controller branch in the device manager. I am running WinXP and have SP2 installed and updated.

I have:
- Upgraded my BIOS, VIA chipset drivers, and USB 2.0 drivers.
- Enabled both Legacy USB support on Onboard USB
- Enabled USB 2.0 jumper on MB
- Tested both onboard and extra set of USB 2.0
- Uninstalled/Rebooted/Allowed WinXP to find new hardware - still no go.

The system just doesn't seem to be aware of the USB 2.0 controller. I am running out of ideas and really would like to get this to work. If you have any information please let me know. Thanks in advance.
