After I reformatted my comp... my usb stop working! I looked in the BIOS and I see nothing with usb. but I'll check again. Someone else want to help me with this? I run a windowsxp pro.
Do you have a Mother Borad CD that has drivers on it. That might be it right there. It sounds like the drivers came out after XP and you have to manually install them. I would look into that first. I have that on my 1 machine that i built. No matter how nnew the XP disc is i use to install the USB drivers are not available after the install. I have to use my Mobo CD to install my USB. Try that first and then post back with your results.
