** 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.
+ For everyone with a Samsung printer the problem of bug 995111 shows up
+ again.
+
[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.
+ Connect a Samsung printer to the USB and print from a completely updated
+ Precise system. You will get printouts with weird characters (at least
+ from the second job on) as described in bug 995111.
+
+ After installing the proposed package all these problems 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.
