Hello, I'm trying to set-up my UPS (ICA RN1100C, a local UPS brand), I've connected USB cable from my UPS to my server, but Unraid doesn't seem to recognize the device and it doesn't show up in System Devices. I've attached the log, it basically said 'can't read configurations, error-71', and at the end it said 'unable to enumerate USB device'.

 

I'm trying to set up NUT and I've tried every driver options available in NUT, but NUT didn't find anything from the scanning process.

 

The UPS manufacturer included a driver CD, which contains drivers for Linux (UPSilon 2000). Is there a way for me to try to add that driver to NUT? If so, how do I do it?

Thanks in advance

It's failing to initialize the device, so it won't be detected by any UPS software, try a different USB port, ideally in a different controller.

Thank you for the response, I tried plugging the USB to another port, but it still gives an error -71 code, although with a slightly different explanation; '

usb 1-2: device descriptor read/64, error -71' 'libusb1: Could not open any HID devices: insufficient permissions on everything'

Is it a driver error?

Looks more like a UPS problem to me, you can see if it works with a different Linux OS, ideally using a similar kernel.
