View Full Version : [ubuntu] Upgrade from 11.10 to 12.04 and USB mouse has problems

July 27th, 2012, 10:57 PM
I have 4 computers and installed 11.10 via CD. The machines worked rather well for several weeks. A few weeks after 12.04 came out I upgraded three of them, and that is when the problem appeared: whenever the machines are powered up, the USB mouse must be unplugged and replugged else it doesn't work. This happens about 80-90% of the time. The other 10-20% the USB mouse does work. The USB keyboard never has this problem.

I have since put together 2 more machines and installed 12.04 directly (also from CD). Those computers also have the USB mouse problem.

I have tried the
GRUB_CMDLINE_LINUX_DEFAULT "acpi=noirq quiet splash"
fix to no avail.
