if it chiped or softmodded
get xbmc (the most recent one you can find),install it to apps,then you can use a psp or other mass storage devices less than 2 gigs to transfer info,all you need is a xbox to usb cabe,just make sure you never unplugg it well it is transfering or it will currupt the flash drive and you will have to reformatt,,i know it works on fat 32 and fat 16 or what ever a psp mem stick and mms is formatted to.plus xbmc has all kinds of stuff that is cool.but other than that i dont think it is possible
