I dont know, if it is bug or feature, but,
USB mouse jumps around (between) /dev/input/mouse0 and mouse1
when taken out and put back in(to same connector), 2.4.0 kernel.
Annoys, should not be the default behaviour, IMHO.

If USB mice had serial numbers (like some USB storage devices
do), then we could tell that it's the same mouse on the
same connector and not change from mouse0 to mouse1.
Currently it looks like a new device attachment.
One possible solution is for you to use /dev/usb/mice,
which is all USB mice merged into one input stream.

Please, if it is possible, make it simple and sensible.
if to have true multihead, with 5 keyboards and mice, I would really wish
that the device numbers are connected to physical holes for plugs,
otherwise anyone (of schoolchildren for example) can do simple nasty
stupid things.
And also it is the dream for true dumbuser with one mouse, because it then
just works out of box.
Or you tell that with USB internal design you can not know physical
connector unique number ?

It's currently not designed for multihead usage.
I haven't looked at it much, but I believe that the
linux-console project is working on that. (?)
(http://sourceforge.net/projects/linuxconsole/)
I agree; your suggestion (same physical device on same connector =>
same logical device) makes sense to me, at least for some
devices, like mice and keyboards. For some devices it could
lead to misuse of the device.

Use /dev/input/mice for this case, not /dev/input/mouse0 .
(Ah, I said /dev/usb/mice earlier; should be /dev/input/mice .)

Yes, we can/do know what physical connector a device is attached
on.
