[Bug 850672] [NEW] "port = auto" does not work with bcmxcp_usb (powerware 5115)

[Tuomas Heino]

Public bug reported:

With the following ups.conf (using the only documented (bcmxcp_usb(8))
value of "auto" for port) nut fails to connect to the ups:

[powerware]
driver = bcmxcp_usb
port = auto

Sep 14 08:59:37 ub3 upsmon[31418]: Communications with UPS powerware at localhost lost

Changing port to an undocumented (and unstable) value below it does connect to the ups & seems to work properly.
port = /dev/bus/usb/006/003
