Synaptics touchpad not found with plugged-in USB mouse
my synaptics touchpad works ok as long as I my USB mouse is not
plugged in when psmouse loads. In this case, the kernel reports that
the touchpad is found and everything works fine.
If I plug in the USB mouse during boot before psmouse is initialized,
psmouse does not recognize the touchpad. When I plug it in
afterwards, both touchpad and mouse works fine.
It is not a BIOS problem (touchpad is deactivated as another pointer
device is found), as the problem exists if I plug the mouse in just
after the kernel is started by grub, but before psmouse is loaded.
I'm using Sarge with a vanilla 2.6.4. psmouse is compiled into the
kernel, the USB stack as modules - so the kernel should know nothing
about the mouse when psmouse is started.
Anyone a idea how to solve this problem?
