[ubuntu] USB devices on KVM occasionally ceases working

view story

http://ubuntuforums.org – Hi, I'm having some problems with USB on Ubuntu Quantal. I have a USB mouse and keyboard, touchscreen and gamepad connected through a USB+DVI+audio KVM. Occasionally, the USB mouse would cease functioning until the machine is restarted, but the USB keyboard will still work fine. Switching to a console and running dmesg reports a barrage of hub_port_status failed (err = -110) messages. There are no preceding errors indicating why this happens, it just happens and at random times. Resetting the KVM also renders the keyboard inactive then and the only way to get the machine to work properly again (Hardware)
