[Bug 483343] Re: USBDUX driver timeout

[Leann Ogasawara]

** Description changed:

+ SRU Justification/Impact:
+ 
+ Per the request of the usbdux maintainer, the following patches resolve
+ a usbdux driver timeout and lockup.  All three patches have landed in
+ 2.6.33 upstream.  Please note that this set of patches depend on the
+ patch to fix bug 563436 (ie re-enable comedi drivers).  I recognize we
+ are frozen for the upcoming release so please consider this for the
+ first Lucid Stable Release Update.
+ 
+ TEST CASE:
+ 
+ I've built a test kernel with the upstream patches applied.  I've
+ received confirmation from the bug reporter (usbdux maintainer) that
+ this indeed resolves the timeout and lockup.
+ 
+ =====
+ 
  This is a patch for the kernel source for Ubuntu Karmic. 2.6.31.
  I'm the maintainer of the usbdux.c driver. I've made a patch which resolves the issue.
