James Courtier-Dutton has the E-MU USB specs. Quoting
"EMU have also now sent me a datasheet for the EMU USB sound cards. I
just need the time to play with them a bit to get them working.

The support for the EMU USB cards has started, and basic support is now
in the latest alsa hg. It only supports 48000 rate, but all the in/outs
should work. Still TODO: Control of extension units that are used for
setting the rate,spdif options etc."
That's the last update, from 2007-10-07. Many people have offered help...
BTW, I guess the 48000Hz rate refers to the hardware's default sample
rate. The E-MU Tracker Pre (and recent 0202/0404 USB firmware) actually
defaults to 44100Hz, so it seems only that rate works with ALSA usb-audio.
