USB fails to PnP

Postby Skar » Mon Dec 28, 2009 3:36 pm


There is something wrong with the USB on this laptop I think.
When I try to plug a mouse in after Mint 8 is running, nothing happens. Not even a light on the mouse.
When I start Mint with the mouse already plugged in, the cursor moves, but it's laggy and slow and impossible to use.

What's wrong? What can I do to fix it?

The laptop is a crappy Fujitsu Siemens Amilo L7310W.

Try adding irqpoll to the end of the kernel line in the grub menu.
[Edit] your original post and add [SOLVED] once your question is resolved.

“The people are my God” stressing the factor determining man’s destiny lies within man not in anything outside man, and thereby defining man as the dominator and remoulder of the world.

mikeyb's suggestion can be correct, however for a Linux newbie it is not easy to understand what to do

Code: Select all

gksudo gedit /etc/default/grub

Find the line
add irqpoll between the quotation marks (save)

Code: Select all

sudo update-grub

Reboot for it to take effect
In earlier versions of Mint this is done differently
Don't fix it if it ain't broken, don't break it if you can't fix it
