[gentoo-user] Xorg 7 and disappearing mouse device

[Iain Buchanan]

Hi all,

a little while ago I posted that I would like to disable the pointer
stick on my laptop but still use the touchpad and usb mouse.  Well, it
couldn't have been simpler!  I have a device for each one
(/dev/input/mouse[0-2] and a common device that melds all three together
(/dev/input/mice).  So I just added two mouse devices to xorg.conf, and
two InputDevice's to my serverlayout, and removed the
single /dev/input/mice and it works great.

It also lets me specify Emulate3Buttons on my touchpad, and not the usb
mouse (which didn't work previously).

Well, almost great - here's the problem:

When I unplug one usb mouse and plug in another (or even the same
one) /dev/input/mouse2 disappears and /dev/input/mouse3 appears, so X
doesn't use it anymore (no mouse device exists for mouse3.

However, if I switch to a console before changing mice, the new mouse
takes the old position at /dev/input/mouse2, then I switch back to X and
it works.

I need to do this plugging and un-plugging because I have a wired
keyboard & mouse at my desk, but I'm frequently moving around our test
facility, so I take my wireless mouse with me.

I don't want to use udev, because I would like a general solution that
works for any of my usb mice (OK, I have a few at different locations :)

Ideally, I would like to make /dev/input/mice use all mice
from /dev/input/mouse2 and up (ie. not the stick or touchpad).  Can I do
that somehow?

Any pointers would be appreciated.  Thanks,

If it is a Miracle, any sort of evidence will answer, but if it is a Fact,
proof is necessary.
