I've got a very confusing issue. I've got a Compaq v5303NR laptop that is having some issues with the 2 USB ports. I did a complete fresh load, loaded all the drivers with the most up to date I could find. Everything in the device manager is found, no yellow !. I can use USB mice and keyboards, but any other USB device shows up as "Unknown Device" in the device manager. I was really hoping a fresh load would fix this. I also updated the bios to the final release, but that didn't help this issue. I've scoured the MSKB for anything related, and followed all of their instructions to no avail. I've checked the permissions on the inf files, I've replaced usbstor system file. I seem to have hit a dead end. Does anyone have any experience fixing this issue?
