I have been working on this on/off all weekend and I STILL cannot get my USB 2.0 ports to work again and they were all working fine for the past 10 months. All 8 USB ports stopped working in 2.0 mode last week. They work perfectly fine in 1.1 mode using the standard Host Controller (BIOS is set for 1.1+2.0) when I disable the enhanced host controller.
are apparently screwed and I have done mostly everything suggested in various web sites to revive them (they had to be overwritten!).
My mobo doesn't have any updated chipset drivers (nVidia) and I simply reloaded my XP drivers to no avail.
Outside of the obvious/common troubleshooting, any one have any thoughts on this issue? I believe an update killed my ports!
