I'll try to be as clear as possible. I recently wiped my system to install Ubuntu Studio 12.04, but it wouldn't boot the installer with my USB mouse plugged in. When I did get everything installed and booted into the system I plugged in my USB mouse and Gnome immediately quit to a black screen, the last line of the message on the screen was
Setting IRQ priorities: start [i8042] irq 12 pid=59 prio=74: OK *Stopping System V runlevel compatibilit[OK]
I was able to switch to tty1, but unable to run startx from there, but lsusb does recognize the devices. I rebooted the system and this happens every time I plug in the mouse or a USB headset. I am able to plug in a USB MIDI Uno device, a USB M-Audio Fast Track Ultra, or a USB external hard drive, but the problem gets stranger.
If I plug in the USB hard drive first, then plug in the mouse it works. But no matter what order I plug things in, the USB headset will crash the system. I found the following in /var/log/syslog after plugging in the USB headset.
I have searched around online and I am unable to find any similar problems.
