Jon-o Addleman, you are correct in that 2.19 is the newest. Despite
this, could you please test for this problem in the newest mainline
kernel via http://kernel.ubuntu.com/~kernel-
ppa/mainline/v3.11-rc2-saucy/ ?

Title:
  USB  sequence errors in snd_usb_usx2y

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Using kernel 3.8.0.19.35, when I plug in my Tascam us-122 usb audio
  device, the log fills up with many of the following messages as soon
  as the firmware is loaded:

  May  5 18:40:31 scaph kernel: [64138.774214] Sequence Error!(hcd_frame=391894 ep=10out;wait=391892,frame=391890).
  May  5 18:40:31 scaph kernel: [64138.774214] Most probably some urb of usb-frame 391892 is still missing.
  May  5 18:40:31 scaph kernel: [64138.774214] Cause could be too long delays in usb-hcd interrupt handling.

  The device seems to initialize properly, but any attempt to actually
  use it (starting jackd for example) results in a few more of those
  messages in the log, and the program fails to connect to the device.

  This is very similar to a bug that cropped up several years ago -
  here's a thread I made on the alsa-user list back in 2006 (!) about
  that one: http://www.mail-archive.com/alsa-
  user@xxxxxxxxxxxxxxxxxxxxx/msg18003.html That bug was fixed in  2.6.18
  so I don't know if it might be actually related or not.

  In any case, I've temporarily solved the issue by downgrading to
  quantal's kernel, 3.5.0-28, which doesn't have the bug.
