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! ;-)
