Has anyone had any success using a usb hub with the a500 or a501? I tried using two usb flash drives, but it will only read one drive at a time. I have NOT tried a usb drive and another type of device because I don't have any other usb devices to try. Thanks Tom Disclaimer: I actually have an a501, but there isn't a forum for that any more. The a501 is just the 3G version of the a500.
