I believe Debian is setup to create those OSS
compatible devices
whenever possible.
It's an option in the ALSA kernel config, and you need to load the
modules accordingly.

This page talks about a `usx2yloader' that I
should run:
http://www.ubuntuforums.org/printthread.php?t=30891
I've installed it and ran it, but it doesn't seem to find the device
either:
$ sudo usx2yloader
usx2yloader: no US-X2Y-compatible cards found
(Yes, I've tried to do the fxload stuff above it manually, too.)
I'm not that familiar with the Tascam, so I give up here (sorry).
Best regards
