Ah, that I knew. The problem is that I'm not seeing any signal values. Or
rather, seeing a constant value. Unfortunately, neither fx2lafw device
works on my Windows box, which is the only thing I can run the CWav
software on to check that the hardware is working properly.

No. It uploads the firmware, and then fails to re-enumerate. Since it finds
it the second time, I figured that was more interesting. Scan logs of that
at the end.

Sure, but it doesn't make any difference. Didn't expect it to, since all
devices belong to group operator with the same permissions as root, and I'm
in group operator.
Thanks again,
