Hi,

This just means the device is not returning data like it should and the 
USB stack detects that and tries to restart.

Try running webcamd in the foreground, and see if there are any errors 
output there aswell. Like request for firmware.

Peek at "ps auxw | grep webcamd" for arguments (remove -B argument).
