I have a RB2011UiAS-2HnD-IN (ROS 6.48.6) and an APC Back-UPS CS 350 with an original USB cable.
I installed the ups package, connected the UPS but the UPS is not detected in ROS. I used the original micro USB to USB adapter.
The port on the RB is OK, if I connect an USB to serial dongle, an USB keyboard or an USB flash drive, all are detected in ROS (System/Resources/USB)
The UPS and cable are also OK, I tested them connected to a PC.
If I power down the RB, connect the UPS and power up the RB, not even the USB port is visible in System/Resources/USB.
I upgraded ROS to 7.2.1, that didn't help too.
What could be the problem?
I'm out of ideas...
