"what info would u like to see?"
It always helps if u post basic info, what PC or laptop(which model),motherboard,CPU,how much RAM do u have, what Win 7x64 or x86 u have, USB2 or 3, ......
All these guys want to help u, that's why they are asking questions. There ar lots of possibilities for USB issues. More info helps to localize the problem from post#1.
Anyway, good luck with that.
