My xbox ftp username is stuck to "None". I can't give it a username and as a direct result, I can't FTP?

How, if at all possible, can I fix this?  I have a flash drive, but it only transfers at 640 KBs per second, as apposed to 3000+ KBs for a network cable.  It takes forever to transfer my games to my new hard drive and I am about to go crazy.
