pwc webcam freeze: usb_control/bulk_msg: timeout
Niels L. Ellegaard
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

The problem is right there, pwc and ohci don't realy like each other. I have
the same camera as you. I used a OHCI computer with motion and it always
stop after 5-10 minutes. It's a known bug :o) look like nobody wants to fix
it... On the other hand, it works perfectly with UHCI. I haven't try the 2.6
kernel on the monitoring box, maybe OHCI is fixed...

You are an insult to my intelligence! I demand that you log off immediately.

I have aquired an USB 2.0 card with an ehci port, and I can load the driver,
but it doesn't find the camera. Has anyone succesfully used a logitech
quickcam 4000 with the ehci-hcd driver?
Perhaps this is because according to amazon the logitech quickcam 4000
camera only does usb1.1. I should have thought of this before
buying the card :)

I have been to 10 shops without finding an USB 1.1 uhci card. They
seem to be history :(
Thanks for all the advices
Niels
