Prices start at about $30, and get very fancy by the time you hit a hundred. > The usb chips are all optimized for std serial port speeds, but midi is > not a std serial port speed, its 31,250 baud falling smack in the middle > between 19,200, baud and 38,400 baud.

That's why they have dedicated midi hardware on one end, and dedicated USB hardware on the other hand. Getting 31.25Kbaud across a 12Mb/s USB1 connection is not difficult. USB2 is 480 Mb/s, and so most of the time is going to be spent waiting for MIDI events to come in. -dsr-
