The light on the front is the volume indicator.  They are horizontal
bars. I think I convinced myself that it doesn't have a hardwired
power light, all lights are under software control.

This may be a case of USB audio's state getting out of sync with what
is set into the device. Here's an experiment I never figured out how
to do, get the device playing music, and then suspend/resume it. That
is different than quickly suspending the device before USB audio has a
chance to set it up.

Actually, do any USB audio devices work with the new suspend code, has
anyone checked other devices? Maybe the first suspend is happening
before USB audio gets everything set up and then when the device
resumes USB audio doesn't know what to do with it. The hub works
because it gets suspended later and USB audio has had a chance to set
things up. What happens if USB audio sends commands to a suspended
device, do they wake it up or return errors, does USB audio check the
errors?

Another experiment would be to switch the initial auto-suspend delay
to one minute instead of two seconds. That would give the boot process
time to finish before the suspends start to happen.
