Public bug reported:
If my USB DVB-T TV Card (Hauppauge WinTV-HVR 900) is plugged in my
Laptop (Thinkpad T43 2668), when the system is suspended, it won't
successfully resume. The resume process seems already started: external
USB Hard disk, USB keyboard, USB webcam have all received power while
the monitor still stays black screen. The process will hang at this
state but if the USB TV Card is disconnected at this point, the process
will continue and eventually the resume will be successful. (There is
typically ~40 seconds between disconnection of the TV Card and the
resume finishes during which there seems no obvious activities with the
laptop e.g. disk I/O).
>From the kernel log, such a pause could be observed:

...
Although the firmware file xc3028-v27.fw is missing in the default
installation of Intrepid as described in Bug #278656, my system has had
the firmware installed manually under /lib/firmware/ before doing the
suspend/resume test and the TV card is working well before suspend.
If em28xx-new, the TV Card driver/kernel modules maintained by Markus
Rechberger, are compiled and installed, there wil be no problem with
suspend/resume.
