pwc webcam freeze: usb_control/bulk_msg: timeout
I have been trying to install a logitech 4000 webcam, but when I use
camstream the picture freezes after a short while and the following
line appears in /var/log/syslog
Sep 3 20:30:22 nissefisken kernel: usb_control/bulk_msg: timeout
I would be very grateful for any advice on how to avoid this problem.
My computer is a x86 with a k7s5a board and Sarge and my own 2.4.21
kernel (See below).
Browsing around on Google it looks like my usb ports are getting
overburdened, so tried the closed source pwcx compressor module. This
modules helped a little, I was able to save 10 snapshots before the
timeout appeared, but in the end I still had a freeze.
The following data is from a test with no pwcx module
