Quickcam Zoom Stopped Working

[mooreted]

Just did an update of Linux Mint and my Logitech Quickcam Zoom stopped working. It has been working fine for months. Cheese, Ekiga, Skype, Zoneminder cannot find the camera any more. It is detected on boot:

10.128026] pwc: Philips webcam module version 10.0.13 loaded.

You probably (unless you are using the latest module for pwc) have to update the pwc module
use the linux-headers that match your kernel version #

In terminal, check

• apt search linux-headers
  i linux-headers-2.6.28-11 - Header files related to Linux kernel versi
  i linux-headers-2.6.28-11-generic - Linux kernel headers for version 2.6.28 on
  i A linux-headers-2.6.28-13 - Header files related to Linux kernel versi
  i A linux-headers-2.6.28-13-generic - Linux kernel headers for version 2.6.28 on
  ls /lib/modules
  2.6.27-11-generic 2.6.27-11-server 2.6.28-11-generic 2.6.28-13-generic

I seem to have the kernel sources:

I searched for pwc in the repos and found 'setpwc". I installed it and ran "setpwc". Not sure if this is the right thing to do, but cheese sees the camera now.

Not sure if that will work after a reboot.
