It is confusing to me also. From reading their docs I thought that the
card was all seperate mono channels lsusb has changed my opinion. I now
belive that Quattro stands for 2 stereo i/o devices not 4 mono i/o devices.
By saying in the docs that it supports 1 channel at 24bit/96Khz I guess
they mean 1 stereo in or 1 stereo out. that is good news to me becasue I
was under the impression that I had bought a turkey with only one mono
i/o channel at 24/96.

Testing again with the new code didn't lock up my mouse and this time
the file actually recorded data although I still cannot capture noise.
Do you have any ideas on how I can adjust the input levels internally
seeing as the card has no apparent internal mixer?
Is this a case of having to write our own mixer device?
Does this part of lsusb have anything to do with mixer controls?
