Start by adding the following. BUS=. At that point a /dev/usb/hiddev. N node. should appear and apcupsd should work fine. If you have several UPSes or you just want to give your UPS a fixed.

So, in these cases, the choices are: Reduce the security level setting of the system (not sure if. Custom build a high security kernel with devfs enabled and make.
