Hello,

after an update I've got troubles with nut. It is not able to connect via usb 
to our UPS anymore.  I dont know wether it is the nut update or the 
kernelupdate or both. In any case, it is difficult to get new rpms for 
CentOS. So if someone has an Idea, what I can try to solve this Problem: 
please help.

Atached are relevant information.

Best wishes,

Hubert Krause
