I'm now getting the something similar. After a reboot, ALSA appears to
be starting OK:

[root@gimel jzitt]# /etc/rc.d/init.d/alsasound start
Starting sound driver snd-usb-audio                        [  OK  ]
Starting sound driver snd-usb-audio                        [  OK  ]
Starting sequencer driver snd-seq-midi                     [  OK  ]
Restoring sound driver settings                            [  OK  ]
[root@gimel jzitt]# 

But jack hangs:

[root@gimel jzitt]# jackstart -R -d alsa -d hw -r 44100 
jackd 0.41.1

I'm also still having the same error from lsusb:

Does this suggest anything (other than what we could tell from my
earlier posts)?
