I have an annoying problem on Xubuntu 12.10. I have a Gigabyte GM-M6800 mouse. I cannot really confirm, but it seems that this started happening with the 12.10 release of Xubuntu where I have my mouse sometimes just go crazy and go to the left-bottom of my screen and stays there. The mouse works really well otherwise.

Some details that might be relevant:

  • Laptop with additional monitor attached to the right
  • Touchpad continues to work, however it's being "pulled" by the left-bottom "center of gravity" created by the issue. That is, when this starts happening, it I can see the pointer when I move it with touchpad, however it gets pulled to left-bottom very quickly
  • Going to Setting Manager, Mouse and Touchpad and unchecking Enable this device for my mouse (says HID 04b4:0033) stops it from pulling the pointer to the left-bottom, however after re-enabling the device, it continues to exhibit the same problem
  • Mouse is attached directly to the laptop (i.e. no additional USB hubs)
  • After unpluging the mouse and plugging it back, the problem disappears
  • Some more info:
$ uname -a
Linux aclap 3.5.0-21-generic #32-Ubuntu SMP Tue Dec 11 18:51:59 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

$ lsusb
Bus 004 Device 002: ID 04b4:0033 Cypress Semiconductor Corp. Mouse

My questions:

  • Any idea why this might be happening?
  • Is there a way to reset the mouse (or any USB device, for that matter)? I.e. to simulate USB unplug / plug in software only?
  • Are there some XWindow-related commands to manipulate the device that might help?
