Hello,

I connected my UPS thru USB :

Code:
bPI usb # lsusb
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 039: ID 0764:0501 Cyber Power System, Inc. CP1500 AVR UPS
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub


but as I can see in system's log, it's continuously reconnecting :
Code:

and the device number is changing as well in lsusb.

I tried on my BananaPI running 3.4.90 and another PC running 3.3.8.

Do you know where this problem can come from ?

Thanks
