Rock band games not working on USB HD

Mar 10, 2010 at 6:20 PM

Hi could you help me please? I did a back up of my game disks and they all work fine except for Rock band games, they load fine but when I try to add the drum set it will detect it but can't add it, Ask for microphone. Tried using a 4 into 1 usb adaptor and connected to the bottom plug because it didn't work pluging it to top. so I have both the HD and wireless blue blinking box in bottom, nothing. I try putting it back the blinking box on upper plugin and doesn't work, help please thank you.

The games I installed on the USB HD are back up disks, not iso's
