Great job on this homebrew :) i just tested it.
It works fine with the SD Card. But no way to make it work for usb devices...
I tested it with 1Gb, 2GB and 8Gb usb keys, with FAT, FAT32 & NTFS file systems. No way.
When I enter in the "USB" section, nothing is shown (only 'USB Path', "Press Home to return the menu" etc...)
The USBkey's light is always turned off.
if i press A in the USB section, i get this DSI error :
