Poll UPS [APC-Smart-UPS-1500] failed - Driver not connected
- 
 I have a APC Smart UPS 1500 connect to pfSense with the configuration being: 
 Local USB to USB
 Driver: usbhidThis should work according to the NUT hardware compatibility list. However I get "Poll UPS [APC-Smart-UPS-1500] failed - Driver not connected" in pfSense system logs. When I run "/usr/local/etc/rc.d/nut.sh start" I get: 
 starting NUT
 Network UPS Tools upsmon 2.7.4
 kill: No such process
 UPS: APC-Smart-UPS-1500 (master) (power value 1)
 Using power down flag file /etc/killpower
 Network UPS Tools - UPS driver controller 2.7.4
 Network UPS Tools - Generic HID driver 0.41 (2.7.4)
 USB communication driver 0.33
 No matching HID UPS found
 Driver failed to start (exit status=1)This is despite the UPS appearing fine if I run "dmesg | grep -i USB": 
 ugen0.2: <American Power Conversion Smart-UPS 1500 RM FW617.3.I USB FW8.1> at us bus0
 ugen0.2: <American Power Conversion Smart-UPS 1500 RM FW617.3.I USB FW8.1> at us bus0 (disconnected)

 ugen3.2: <American Power Conversion Smart-UPS 1500 RM FW617.3.I USB FW8.1> at us bus3
 (could it be because it appears to be connected to both bus0 and bus3?)I have tried: 
 different usb port
 saving the configuration again.
 set various extra arguments.
 restarting pfsenseWhat else could I try?

 After a few USB re-plugs and restarts of pfSense it finally figure it out and started working.
