What on earth are you trying to do? I see you're trying out both  
serial (liebert) and USB (usbhid-ups) connected drivers, without  
reference of which one worked in an earlier version. I also see that  
you're attempting to run multiple driver instances in parallel (most  
likely, unintentionally) for the same UPS. This is never a good idea.  
Always make sure that when you're trying things out, the leftovers  
from earlier experiments are stopped.

Since the VID:PID combination of your UPS is not supported (not even  
in the development version), I suspect you've used the serial driver  
before. If that's the case it should still work, but most likely not  
if you connect the USB interface at the same time (in many cases,  
devices with both serial and USB share a lot of interface hardware  
internally). Chances are that your UPS might also work through USB,  
but I have never seen that before.
