Optical mouse misbehaving.

I have an Acme optical mouse model MS04 which is intermittently stopping to respond while I am under XFCE4.10. I am using:
Code: Select all
uname -a
Linux edbarx-pc 3.2.0-4-rt-amd64 #1 SMP PREEMPT RT Debian 3.2.73-2+deb7u3 x86_64 GNU/Linux


CPU: T4400
Chipset: ICH9 (Intel)

The mouse misbehaves when I use it after it has been left idle for some time.

Any helpful hints are much appreciated.

Thanks.

You could try opening up a terminal and running:
Code: Select all
dmesg -w

Then wait until the mouse misbehaves and see if any messages are written to the kernel ring buffer.

An intermittent problem would suggest hardware failure, either the mouse itself or the cable/connectors.

EDIT: Also, what does "misbehaves" actually mean?

If it just turns off, try disabling USB autosuspend:

I am associating the misbehaviour to a dark brown patch in the middle of the mouse pad. If I remember well optical mice are not sensitive to red/brown colours. If anyone can confirm this the solution would be as simple as replacing the mouse pad.

Two wireless optical mice here - both on a very dark brownish red desk, neither has any tracking problems.



Why don't you grab a sheet of paper from a printer and put it over your mousepad and see if the problem persists? Easy, cheap, and simple test for the problem.








Also check the battery status ( if it is a wireless mouse ), it may be that the batteries are just plain getting weak and the receiver is just slightly out of range sometimes.
