Im having the same problem. I have a huge amount of pintech 64 usb flash drives which can be formatted, for backup, from the xbox yet pc's, after format, can not find the usb flash drive. I have modded a xbox dongle (plugs to xbox) to usb (female end) and usb (male end) to (xbox controller end). Basically I cut the dongle in half / then the usb extension the same way and WOW: you will end up with a 21 foot xbox controller cord that works! hehehehhe
However, if anyone knows any work around with this. It would be so awesome! If more information is needed I will try to gather it.
I have done the megaxkey downloads yet no joy. The AR software works when I insert the oem memory card into the controller then into the usb of the pc. That does work.
My hope is to get this to work with the 64meg usb flash drives I have then try and send it to the masses. Thank you for your time.
Take care
