Skype makes webcam disappear from lsusb

Hi all,

I have a logitech QuickCam Deluxe for Notebooks, and up until my last pacman -Syu last weekend, it worked with skype as long as I started skype using

export XLIB_SKIP_ARGB_VISUALS=1 && skype

It has always worked with xawtv -c /dev/video0, and it continues to do so.

Now it doesn't work with Skype no matter how I start skype (normally or after exporting XLIB...) I get "No video devices found" on the video page in Options.  AND, after I quit skype xawtv doesn't work any more, and the device has disappeared from lsusb.  It has to be unplugged and plugged into a _different_ usb port to show up again.

I have a thinkpad X61.  Any ideas?  Thanks in advance!

Re: Skype makes webcam disappear from lsusb

Look at the output of dmesg and see if the device encountered a bus disconnect.  If it did, there may be a reason logged there as well.  Also, if there was a bus disconnect, check before it in the dmesg output to see what may have preceded the disconnect.  Also, check your logs in /var/log for clues.
