I have some problem when updating NUT. I have server with 4 UPS connected.
When I starting upsdrv and upsd and after sometime (1-2 minutes) I can't get
data from ups's
# upsc a...@localhost battery.type
Error: Data stale
and errors in /var/log/{syslog,debug,daemon.log}
usbhid-ups[2385]: Got disconnected by another driver: Device or resource busy
If you want to monitor multiple UPSes through usbhid-ups, you *must*
make sure that each one can be uniquely identified through the
"vendor", "product", "serial", "vendorid", "productid" and "bus"
regular expressions (see 'man 8 usbhid-ups' for an explanation how to
use these).
If you don't do this, the drivers will connect to the first device
that matches, which may mean that all four instances may attempt to
connect to the same UPS. Your setup may have seemed to be working
before, since previously we didn't check for this condition. Now the
drivers will bomb out when another driver attaches to the UPS they are
monitoring.
Best regards, Arjen
