to diagnose this, we are going to need a usbmon trace. You can find instructions on how to do this at https://www.kernel.org/doc/Documentation/usb/usbmon.txt
also, what package does that 'hp' app come from ? make sure you have the latest version of that.
Created attachment 559788 [details] usbmon log when trying to print to Photosmart C3150 printer. Tried to print a few files. Thanks for looking at this.
Version of hplip is hplip-3.10.6
*** Bug 781762 has been marked as a duplicate of this bug. ***
I discussed this problem upstream with the USB maintainers. Here's what Alan Stern replied: I took a look at the source code for the hplip package. In io/hpmud/musb.c, the musb_raw_channel_close() routine always calls usb_clear_halt() for each bulk-in and bulk-out endpoint that it uses, whether the endpoint needs it or not. If one of those endpoints had a read or write going on in another thread at the same time, the usb_clear_halt() call would cause the WARN to trigger. It's hard to tell exactly what the program is doing. You'd think that all I/O to a printer would be serialized, and ongoing reads or writes would be completed before anything was closed. But the use of multiple threads and callback routines makes the code difficult to follow. Anyway, removing those usb_clear_halt() calls would most likely eliminate the problem. Of course, they might be needed for some printers. Still, it's best not to clear a halted endpoint until you know that it is halted, and then it is best to clear the halt condition right away instead of waiting until some I/O channel is closed.

Adding myself to cc: . saw something similar with DVB-T and mplayer.
This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
