[Nut-upsuser] APC 750VA UPS not recognized by NUT?

Hi, Charles!

Situation 1:
Step 1: APC UPS plugged
Step 2: Cyber-power UPS pluged
Step 3: upsdrvctl start, Cyper-power UPS recognized

Situation2:
Step 1: APC UPS plugged
Step 2: upsdrvctl start, APC UPS recognized
Step 3: upsdrvctl stop
Step 4: Cyber-power UPS pluged
Step 5: upsdrvctl start, Cyper-power UPS recognized


Situation3:
Step 1: Cyber-power UPS plugged
Step 2: upsdrvctl start, Cyber-power UPS recognized
Step 3: upsdrvctl stop
Step 4: APC UPS pluged
Step 5: upsdrvctl start, Cyper-power UPS recognized

I check /proc/bus/usb/device, the cyper-ups is always ahead of the UPS one if thay are all plugged.

That comes another question: If two UPS device with different driver plugged, and the two drivers are both configured, are they both recognized?

I have only read of information of upsd pointed from User Manual. I will read and learn more about that.
