well, i've found that it's working fine out the box, it's actually a
call to luvcview -L -d /dev/video1 that breaks it.
I'm very surprised by that. luvcview -L doesn't modify the hardware
state. Maybe only the first stream attempt succeeds ? Could you try
running luvcview -d /dev/Video1 multiple times in a row ?
You are right, the first time luvcview -d /dev/video1 works fine, the
second it does not.
So the hardware probably crashes when the stream is stopped. Bad hardware :-(
This will be a bit hard to debug. We need to find out what makes the hardware
crash. It's probably a command send by the driver when stopping the stream, or
the lack of an expected command before restarting the stream.
The easiest way I can think of to try and debug the problem would be to
capture a USB trace when using the camera under Windows. Do you feel confident
enough to try that ?
Unfortunately I don't have a windows machine at hand, at work i have
only mac os x machines. Are them any useful?
thanks,
riccardo
