Please upgrade to r188 and retry. The last message ("Dequeing buffer 0")
should now provide some more information.
Does the driver stop printing messages at that point ? Does it print
any "Dropping payload (out of sync)" message while you use the webcam
*before* the freeze happens ? What are the few last messages printed by the
driver *before* the first "Dropping payload (out of sync)" message ?
You will have to check the system log files to get the messages
before "Dropping payload (out of sync)", as the kernel log buffer isn't big
enough to hold all messages. Kernel messages are in /var/log, probably
in /var/log/kernel.log (this can change depending on your distribution).
Best regards,
Laurent Pinchart
