Yeah, I think you missed my second post, the ALSA driver appears to 
support the 2x4.

I don't think it matters for MIDI -- I looked at some numbers at one 
point and concluded that 1.1 would be enough for a large number of MIDI 
devices.  If you had other USB devices sending a lot of data (e.g. 
audio) and they were all on the same 1.1 bus, yes they would probably 
compete.  But for a mouse, pc keyboard, and the MidiSport, I think you'd 
be fine.  No promises! :)
