Hello, ur from hwluxx, right? Anyway, are all u settings, except the 2.5-x-x-x, on AUTO/SPD? If u have ICQ try to add me, and we will find a solution, i'm sure. Regards @Stonekiller Try a different Bios, maybe the 510-3, some others have problems with USB. @Abducted The description of the different bios versions is correct here, imho.
