Tried to post this by gmane to keep the thread history accurate, but it
failed for some reason I don't care to discern at the moment. So I'll just
reply to an earlier message of mine.
This is in response to Parisson's request for more info on system

Could you tell me what kind of setup you have (distro, kernel version,
version, etc..) ? Also do you use any special modprobe
rules described in
Joe's blog page above ?
Hi (and thanks for the driver!),
I'm on ubuntu 12.04 with lowlatency kernel, Jack 1.9.8.
$ uname -a
Linux dlm-A6200 3.2.0-23-lowlatency #31-Ubuntu SMP PREEMPT Wed Apr 11
UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Synaptic GUI says jackd2 is 1.9.8~dfsg.1-1ubuntu1
CPU: Intel(R) Core(TM) i3 CPU M 350 @ 2.27GHz
Oddly, after claiming that I couldn't get it to work with a buffer smaller
than 1024, I did get good mic input today with a 512 sample buffer. But
then, SuperCollider started behaving oddly ???? It seemed like some of the
audio processing just wasn't happening, although mic --> reverb --> DAC
sounded fine. I've asked about that on the sc list.
I'm in China, where blogspot is not a happy place. I have one machine with
a proxy service, but that's been down for weeks. So I'm afraid I'm unable
at the moment to read that article. Are there some particular nuggets of
wisdom you could copy and paste to the list? (So, no, I'm not doing
anything special with modprobe. I did find that I have to remove
snd-usb-audio, and then re-probe it, or the FTPro doesn't work, but I
haven't configured any rules [nor do I know how to configure rules :-p ].)
