Description Brian 'netdragon' Bober 2004-09-25 02:35:01 UTC

I have a Logitech Cordless Mx Duo set with a Logitech MX700 cordless
mouse connected to a Belkin Soho-4 port PS/2 USB KVM switch via PS/2 and if I
switch to my Windows laptop and back, I lose all mouse functionality. I can
regain it by removing the mouse from the KVM switch and then re-attaching it.
This wasn't happening with the Microsoft Intellimouse Explorer.

Additional info:
I still have the patch applied from
http://bugzilla.kernel.org/show_bug.cgi?id=2082

I noticed that on rare occasions the mouse doesn't freeze. In
that case, it just goes haywire for a second. I did notice that at
those times, I get the same notice I did from the patch I mentioned in
comes from http://bugzilla.kernel.org/show_bug.cgi?id=2082 so that patch seemed
to reset the mouse when it doesn't freeze. Otherwise, I have to disconnect the
PS/2 plug and recoonect it.

This is probably a hardware issue, but I was wondering if there is any way the
drivers could do the equivalent of a manual replug of the PS/2 port.

Comment 3 Dmitry Torokhov 2005-04-01 08:10:57 UTC

Try doing (with your mouse connected)

    echo -n "reconnect" > /sys/bus/serio/devices/serioX/drvctl

where serioX is serio port where your mouse is connected.

Also, what device are you using (/dev/input/mice or /dev/input/mouseX)?
