Hi Mattia, hi all,
it actually _is_ a bios problem. If I deactivate "USB BIOS
Support" (no "USB legacy support" in my BIOS as mentioned in the
tread) I can leave the mouse plugged in during boot. But then I
cannot use the mouse in the BIOS. The problem was that the BIOS
"help" only said sth about deactivating boot from USB diskette/CDROM.
My configuration for the archive:
- Disable "USB BIOS Support"
- psmouse compiled in the kernel (2.6.4)
- uhci/ehci compiled as module
- no hotplug (as it is started after init it should not matter if it
runs - at that point psmouse knows about the touchpad)
Thanks to all for helping!
