Same happens to me on Dapper Drake 6.06.1 ... Using spca5xx too, webcam is a "Genius VideoCAM Express"
When I plug in the cam, and I use a webcam program (amsn in my case), and I stop the webcam transfer in amsn, and I plug the webcam out, everything hangs for a second or 2 (music etc. stops for 2 seconds too) and then khubd starts to eat up 99% CPU Everything is still running smooth enough to be workable (thank god for linux' multitasking capabilities), but the CPU fan is constantly on, and obviously, some big programs react slow now... When I plug out other USB devices, and I plug them back in, they don't work anymore!!! (my Logitech G5 USB mouse for example) -- Use cpu 100% and not reboot/halt https://launchpad.net/bugs/32164 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
