Yes us428control is indeed already running, spawned by the hotplug scripts
alright. How could I miss that? :)
OK. The first thing I tried then was killing it and restarting it by hand:
us428control -v2 -D hw:1
By tweaking some knobs and faders it seems that its working. I have the
verbose feedback OK, or so I think. Below, you can find some data that
I've collected here. Please check if it's the same or similar that you
find for the US-428.

Nope. INPUT MONITOR never gets lit, despite the verbose output of
us428control saying otherwise (see below).

Neither of those leds get ON, no matter how much I try to play with them.
Only darkness I see.

Tried several positions. Can't hear a thing. No output, only silence

Hmmm. Is it planned any time soon? Can I help in any way?

YES. Capture works. I've tested with `arecord -D hw:1 take1.wav` and I can
hear my guitar. Obviously I had to feed the captured file into the onboard
soundcard to get to ear it.
After all, it's only playback that's missing. Oh, and no leds too.

As I noted, I'm testing on two quite different machines, a desktop and a
laptop. The desktop one seems to be using UHCI (although ohci, uhci and
ehci modules are all loaded in). The laptop one is OHCI for sure and only.
AFAICT, the behaviour is quite the same on either system. No playback
sound, at least via PHONES output.
Now follows the data I collected while watching `us428control -v2 -D hw:1`
output. Hope it sheds some light.
