** Description changed:

  My Canon i560 was working fine until the update two days ago. Now it fails 
every single job, printing half a page and then ejecting the page when a USB 
reset is issued. Same printer works fine when printing through Windows in 
Virtualbox with USB passthrough.
  Summary: the USB backend "improvements" have rendered my printer useless with 
CUPS. Unloading the usblp module makes no difference - the USB reset is what 
aborts the print job.

+ [IMPACT]
+ 
+ Everyone with a Canon inkjet connected to USB and also users of some
+ other printer models on USB get printouts with the last page being
+ incomplete. This happens for every job.
+ 
+ [TESTCASE]
+ 
+ Unfortunately, for reproducing this bug one needs the actual hardware.
+ 
+ Connect a Canon inkjet (or other models mentioned in this bug report) to
+ the USB and print from a completely updated Precise system. The last
+ page of each job will come out incomplete.
+ 
+ After installing the proposed package the problem should disappear.
+ 
+ [Regression Potential]
+ 
+ Regression risk is very low. The fix is not doing the USB device reset
+ on the printer after the job for most printers. The fix contains an
+ exception rule for Samsung printers and Prolific Technology
+ USB->Parallel adapters, to avoid reoccurring of bug 987485 and bug
+ 997040. It is still possible that some printers are treated incorrectly
+ in terms of whether they need a reset after the job or not. As most
+ printers work both with and without reset this risk is very low. All
+ reported problems are solved with the proposed fix.
