I'm also experiencing a similar problem. Logitech M515 mouse with Unified Receiver about 40% of the time on powerup mouse doesn't work pulling out nano receiver and putting it back it seems to resolve issue.
typing commands: sudo modprobe -r hid_logitech_dj sudo modprobe hid_logitech_dj also resolves the issue about 90% of the time, occasionally have to repeat the above 2 commands again, or a 3rd time before mouse behaves, but once it behaves, it stays working until next reboot. (Timing issue somewhere in updated hid_logitech_dj code?) triple boot machine, Windows7/Ubuntu 10.04/Ubuntu 12.04 64bit, problem only occurs in 12.04 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991932 Title: Logitech Unifying Receiver can't reset device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/991932/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
