i have a ac2 on ros v7 that is not recognizing the usb port in system-ups package, but under resources-usb it show i have connected an apc ups. the same problem was in ros v6.
i have a ac lite with the same config and same ups that is working normally. i tried the same ros version, then i tried to upgrade, but the port is still not working.
hap ac lite:
any help?

hap ac2:

It seems that UPS package in ROS doesn’t support that particular APC UPS model. The best thing you can do is to ask support@mikrotik.com to support it somehow.
Hi. Did you manage to solve the problem? I have a similar problem. HAP AC 2 sees via USB, but does not see the port, while the same UPS through the same cable perfectly recognizes HEXS. ROS 7.18.2.
Same here. I am using APC SMart-UPS 1400. Does not detect the USB port somehow. ROS v7.19.2
