That's wierd. When i remove my USB mouse, the device does not =
disappear. No
matter how i boot, i have mouse1-3.

What distro are you using? Do you have devfs? Or udev?=20

This will make a big difference. I am guessing that you have devfs if
devices are disappearing on you.

I am assuming the externam devices are USB. I can't imagine any =
sensible way
to get USB devices to load before builtin devices. Do you have the USB
modules compiled directly in the kernel? That might fix it by chance.
Otherwise, try making both drivers LKM's and change the order in
/etc/modules-${KERNEL_VER}

Good Luck!
