    Hi Guys,

    Just installed Ubuntu and loving it so far.

    I'm having a problem with my mouse though! It scrolls through documents/web pages really fast.. I need to unplug the mouse then plug it back in to get it to slow down.

    Just wondering is there a command/script that would refresh or disable/enable the usb devices in the computer. I could then put this in the "startup folder"..?

    Cheers!

    You can use xinput to disable/enable the mouse on the fly.
    As root: "apt-get install xinput"
Scan for your mouse: "xinput list | grep -i mouse"

    Now you will see a list of devices matching the "mouse" string.
    You can now disable the mouse with the matching string.

    For example, on my machine the list returns: 
    ⎜   ↳ ImPS/2 Logitech Wheel Mouse             	id=9	[slave  pointer  (2)]
⎜   ↳ Macintosh mouse button emulation        	id=10	[slave  pointer  (2)]

    Now, you can disable the mouse by subsituting the 1st device string above with the following: 
    ENABLE:
xinput set-int-prop "ImPS/2 Logitech Wheel Mouse" "Device Enabled" 8 1

    DISABLE:
xinput set-int-prop "ImPS/2 Logitech Wheel Mouse" "Device Enabled" 8 0

    Forget the desktop icon, add these two aliases to your .bashrc file: 
    alias mouse_enable='xinput set-int-prop "ImPS/2 Logitech Wheel Mouse" "Device Enabled" 8 1'
alias mouse_disable='xinput set-int-prop "ImPS/2 Logitech Wheel Mouse" "Device Enabled" 8 0'

    Now from your shell, just type mouse_enable or mouse_disable to enable/disable as required. You could use the following script to do the job, or even set the mouse on and
    off using cron/anacron entries. shopt is required for non interactive shell sessions, so you need that line to expand your newly defined aliases, otherwise it won't work.
    #!/bin/sh
shopt -s expand_aliases
source /home/<your_name_here>/.bashrc
mouse_disable
mouse_enable

    Thanks so much, Naikon!

    The problem seems to have sorted itself out now. No need to unplug mouse anymore!

    Cheers! :)

    Glad to be of some service :D

    Welcome to the land of Unix/Linux btw. I think you will be around for a long time. It's nice to actually see somebody treating the OS on it's own merits and not expecting an open source version of Windows. Ubuntu will serve you well.
