Hi, colleagues!

Something strange happens with a server. I am attempting to connect management
interface of UPS with server via USB.
In console I see a lot of errors:

Mar? 7 13:42:04 xxx kernel: ugen2.2: <POWERCOM Co.,LTD HID UPS Battery> at
usbus2
Mar? 7 13:42:05 xxx kernel: uhid0 on uhub6

I have changed USB-cables, USB port on the server - without success.
On another server this problem is absent.

FreeBSD version: FreeBSD 11.1-STABLE #1 r329364M:

Any ideas?
