[qcam] qc_lock_wait: acquiring lock for 0x378
[qcam] qc_lock_wait: got lock for 0x378
This is the call to qc_lock() in sane_start(). xcam and xscanimage
also hang, but it gets farther; see the debug output below. It looks
like the camera gets into a wedged state somehow. Opening and closing
the device for every scan doesn't help the problem, but doing
sane_init() and sane_exit() around each scan does; everything works
fine if you do that.
Presumably colour QuickCams don't do this, or someone would
have noticed it. Before I try to track down the problem, could
someone else with a B&W QuickCam try running xcam or xscanimage, and
see if they get the hang too? Perhaps my setup is broken somehow...
Thanks in advance!
