M4A79T deluxe or W7 USB problem?

[Frejoh466]

Ok for a while ago I got my new motherboard M4A79T deluxe, when I got that I also got Windows 7, but here is the problem my USB port aren't working right...  I had some weird problems with my USB mouse but it seems like it got fixed somehow.

But now when I'm trying to get big files (50+ MB) my USB port just crash... it just lose all connection to it (The USB is working) it only work to transfer small files or to use a U3 USB, I don't know if it is the Windows 7 64 bit or if it is my new motherboard. I have tested with all my USB port so they are not broken, and there seems to be none USB drivers ether...

So anyone know why this would happen?
