Looks like this is pretty well supported

I did find http://www.pps.jussieu.fr/~smimram/tascam/ , would that
indicate that its somehow possible? It seems the company itself is
uninterested though, so that would be a big minus

Probably a non-issue for me as I'm fine with 48 kHz duplex the whole
way.


Concerning my 2nd question, would anyone of a more hardware-technical
bent be able to tell me if none/any/all of the above interfaces have
sufficient gain for an SM57 (supposedly 50 dB and above). Its tough to
find such specs for any of the interfaces...
