evdev is not working when you hotplug devices

Bug Description

The evdev mouse protocoll works fine for configuring all your mouse buttons,
except if you are hotplugging your usb mouse.

So if youre mouse is plugged in during xserver starts, it works fine. But if you
then plug it out and in again, your cursor is not moving until you restart the
xserver.

I got on this problem, cause I use an usb-kvm switch.

I can confirm this, its a missing feature in Xorg.
Maybe Xorg 7.2 can handle Hotplug input Devices.
the old way over /dev/input/mice is a "workaround" because the Kernel handle the hotplugging and map all mice on this device.
For the event devices there is no such generic device. So the device file exists only when the device is present.

I've the same Problem with my Bluetooth Mouse, because of the limitations of the old way I can't use all Buttons :-/

Hi, is this still an issue with the versions in Dapper or Edgy?

this is still an issue in edgy.
as heiko mentioned, there is no generic device for evdev (or at least i'm not aware of such thing).
so if you set up your mouse with evdev you have to specify something like

Option "Device" "/dev/input/event1"

but the problem is, your pointing device isn't always 'event1' if you're hotplugging your devices.

Please test with Feisty which as of today has 1.1.5, and that should support input-hotplug.
