Re: usb device names on a multiseat-X machine

Option "Phys" "usb-0000:00:10.1-1/input0"

The physical address is needed to assign each keyboard to the right
seat. If I leave it out, one user will have two mice and two
keyboards and the other will have none, because the first X server
will grep all input devices it can find.

As long as no other usb device is plugged in while booting, the above
option works perfectly. It there is something else plugged in while
booting, the address seems to change and evdev can't find the
keyboard any more. (The same goes for the mouse.) That's why I'd like
to get rid of the physical address there and use
Option "Name" "HID 1267:0103"

But if I do this, (EE) Keyboard1-usb-0000:00:10.1-1/input0:
AbsoluteTouch: 'DIGI_Touch' does not exist.
Are the keyboards 'different'? If so, you can create rules for udev
to create unique device files under /dev.

Wolfgang used X-No-Archive on his post in col.x, so I can't give you a
groups.google link, but that post should be there in recent traffic from
that newsfroup. He already tried that. It didn't work. evdev
apparently has problems with using pathnames or vendor/product IDs. I
don't know precisely how to fix this (and it might involve hacking on
evdev to fix it.)
