Step 1: Cyber-power UPS plugged<br>
Step 2: upsdrvctl start, Cyber-power UPS recognized<br>
Step 3: upsdrvctl stop<br>
Step 4: APC UPS pluged<br>Step 5: upsdrvctl start, Cyper-power UPS recognized<br><br>I check /proc/bus/usb/device, the cyper-ups is always ahead of the UPS one if thay are all plugged. <br>
<br>
That comes another question: If two UPS device with different driver
plugged, and the two drivers are both configured, are they both
recognized?<pre><br> >

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