benq X805 wireless mouse erratic

[Philippe A.]

Hi everyone,

I have just purchased a Benq X805 wireless keyboard and mouse combo. The
keyboard works great. However, the mouse behaves erratically. Every minute
or two, the cursor starts jumping around and clicks are registered in
response to simple movement. This behavior is seen in X only. I couldn't
reproduce it in a text console.

I have noticed many of the following in dmesg.

psmouse.c: bad data from KBC - timeout
psmouse.c: Wheel Mouse at isa0060/serio1/input0 lost synchronization,
throwing 3 bytes away.
psmouse.c: bad data from KBC - bad parity

Both receiver cables are plugged in PS/2 ports. There is no driver CD
shipping with those, so really I think they should Just Work.

This behavior reminds me what Microsoft mice were doing back in RH9 days.
These wouldn't exhibit exactly the same symptoms, except that they didn't
work any better in a text console.

I am going to perform a few more routine checks and report back when I have
more news. In the meantime, please do not hesitate to post any suggestions
you have.

Thanks!
