My laptops don't have 'real' MIDI ports. One of the desktop machines 
does, courtesy of its Audiophile 2496, but I have no 'real' MIDI cables.

It's a proper high speed USB2 hub that claims to be compatible with 
USB1.1. I have a USB2 scanner hooked up through it, and when I scan 
high-res 24-bit color, it scans at USB2 speeds. Having accidentally used 
it ONCE on a different machine that had only USB 1.1 ports, I *know* the 
speed difference! ;-)

Not yet. I plan to.
