It's going to be difficult to do a MITM attack because iirc, the 360 encrypts the data going over USB so that 3rd-party peripheral makers have to get a license from Microsoft to make a supported peripheral. Of course there always seems to be some sort of chink in the armor like with Wii. But I'm sure Microsoft is probably a lot better at writing operating systems compared to someone like Nintendo. (To those who are interested in this type of thing: In the Wii's case it was using a pair of tweezers to glitch the memory chip into spewing Wii OS code that revealed that Nintendo was using strncmp to compare SHA1 hashes instead of memcmp which rendered the entire authentication system open to attack because if you can create a hash that has a leading null-byte then it will not be compared. So even though all games and firmware updates were RSA signed, this exploit bypassed everything. )
