small USB MFC for perusal.

[Julian Elischer]

This cleans up most of the remaining MFC issues..

http://www.freebsd.org/~julian/usbdiff

these are cosmetic changes to: 
M if_aue.c
M if_cue.c
M if_rue.c
M uftdi.c
M uhci.c
M usbdi.c
M uscanner.c
M uvisor.c
M uvscom.c

and consists of:

ID additions for some devices and probing additions for the Clie 350
one copyright addition
and two bits of code missed in the main MFC. (tiny)
A couple of variable renames.

anyone care to comment?

I'd send this to the USB list but it's almost dead..
