The above is a problem with the Gentoo startup script. We don't  
provide startup scripts, so you'll have to as someone from Gentoo for  
help.

I think it is a udev problem, ie the permissions for the device node  
is not changed to allow the driver process to connect. You can verify  
if this is the case by running the *driver* with root permissions:

     /path/to/usbhid-ups -u root -a MGE-Ellipse600
