[Nut-upsuser] drivers fail after upgrade

[Noel David Torres Taño]

Hello all:

I've detected in several machines that an upgrade (I do not know exactly (yet) 
which package triggers this, but I suspect of nut package itself or udev 
package) makes communications with the USB UPS fail.

The immediate culprit is that the driver can't communicate with the UPS, 
kernel saying that can't claim it.

Fixed it with
udevadm trigger --action=add --property-match=ID_SERIAL_SHORT=(ups' serial 
number here)

Is there a way to avoid the failure to happen?

Thanks

Noel
