Hey guys, having some issues with this hu. First off it keeps freezing and then not responding so I need to reset it (it will however keep playing whatever audio source was on at the time). But when it does work it won't pick up any usb drives or sd cards. I know my sd works as I can use it to get into test mode! But even in the wince test mode it won't pick up usb drives. Any solutions guys? I'd be grateful if you tell me to re flash to link me to the files so most I've found on here are dead.
