This begain affecting me as well upon upgrade to Quantal beta today. I have the same model Logitech USB receiver (mouse+keyboard) connected (see lsusb). Unplugging and replugging also worked for me. The relevant error message appears to be "reset_resume error -1", which is starred in the filtered dmesg output below (two instances for two separate resumes). Given that this is a power management method implemented by USB drivers, I'm assigning the bug to linux-image-3.5.0-14-generic. I'm also including detailed lsusb output for the receiver and its hub. > lsusb Bus 005 Device 003: ID 046d:c517 Logitech, Inc.
