Bug Description
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.
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.
