So you are on BIOS19?
& you are sure that it's
any USB device as it usually comes down to 1 or 2?
Have you tried just V1.1?
Unfortunately this seems to be affecting a small no. of users across various mfrs nF4 boards - I know for a fact that it's been reported on both DFI & MSI nF4 boards also so it's a fair bet that there will be others too
