Title:
  raring-updates: regression: 3.8.0-24.35 causes sporadic failure of USB
  audio devices

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  The 3.8.0-24.35 kernel update in raring introduced sporadic failure of
  USB audio devices. The symptoms are that the device suddenly stops
  working and you get the following dmesg output:

  [ 7532.838274] cannot submit urb (err = -18)
  [ 7532.838283] cannot submit urb (err = -18)
  [ 7532.838291] cannot submit urb (err = -18)
  [ 7532.842224] delay: estimated 288, actual 96
  [ 7532.922160] delay: estimated 432, actual 96

  This bug has been introduced by the following commits (UHCI: implement new semantics for URB_ISO_ASAP, OHCI: implement new semantics for URB_ISO_ASAP):
  https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c44b225077bb1fb25ed5cd5c4f226897b91bedd4

  A fix has been released (USB: fix latency in uhci-hcd and ohci-hcd):
  https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e1944017839d7dfbf7329fac4bdec8b4050edf5e

  The fix hasn't been backported to 3.8 yet, but as this bug was
  introduced to raring by pulling upstream kernel changes, it would be
  nice to backport the fix to raring as soon as possible.
