Keyboard/mouse non-responsive in Ubuntu 10.04 guest -> USB filter setup issue

[Adam Dorsey]

Host: Ubuntu Lucid 10.04

Guest: Ubuntu Lucid 10.04

During install the keyboard and mouse worked. On first boot of the guest operating system the keyboard worked, then updates were installed. During boot of the guest, the keyboard appears to work, but once guest gets to GNOME desktop, the keyboard and mouse are both nonresponsive. Host key will not disengage the keyboard from the guest either, forcing a hard reboot. This is not the issue with the host screensaver previously reported; screen saver never activates on host and keyboard/mouse never works in guest.

More info: We tried killing the VirtualBox instance via SSH after we lost keyboard and mouse. Upon doing so, keyboard and mouse were still non-responsive in the guest, but unplugging and replugging both got them responding again.

So after the last comment we took the results to the logical conclusion: we booted the VM, the mouse and keyboard were unresponsive, then we unplugged and replugged the mouse and keyboard. That workaround made the mouse and keyboard start working again in both the host and the guest.

And that only worked for a short period of time before the virtual machine completely froze and caused the keyboard and mouse to stop responding again.

OK, we resolved the issue. The filters for the USB keyboard and mouse were checked under the USB tab of the Settings. Upon unchecking them, the keyboard and mouse worked as expected.
