Hi Christopher I may have come across an idea of where the problem lies, but I don't have the technical understanding to know how this causes the problem. I started by looking at the log files (syslog and kern.log) using the System Log Viewer, then started to use Google to try and get some understanding of what is happening. One thing I looked for was references to ehci_hcd and came across this web page
http://www.geekdevs.com/2010/04/solved-unable-to-enumerate-usb-device- disabling-ehci_hcd/ So I tried commands given there to disable ehci_hcd, that is cd /sys/bus/pci/drivers/ehci_hcd/ sudo sh -c 'find ./ -name "0000:00:*" -print| sed "s/\.\///">unbind' Having done that it appears that the webcam still works and does not disconnect. When it is manually disconnected and reconnected it connects using ohci_hcd. Of course I do not know the full implications of disabling ehci_hcd, except that I understand that USB support is demoted from 2.0 to 1.1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/784280 Title: Logitech UVC webcam keeps disconnecting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/784280/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
