You use official Armbian? I assume you have internet connection on that board? What about dmesg after you plug and unplug that usb device? Link to comment Share on other sites More sharing options...
Geralt Posted February 22, 2020 Author Share Posted February 22, 2020 I was logined on the root. If I change user If I use armbianmoniotor -U it works armbianmonitor.log I instaled armbian from https://dl.radxa.com/rockpi/images/third-party/ After use dmesg in line 657 is information about this device. dmesg.log Maybe i should install different Armbaian?

Geralt Posted March 1, 2020 Author Share Posted March 1, 2020 Hello! I resigned from Armbian because I fought two weeks and not every thing working in this linux. I insaled on my Rock Pi 4 lastes (and others too) Armbian. This is terrible which I had to instaled and changing on my Rock Pi 4. And the end wifi disconnect after about 10 minuts of operation. I had to reboot computer every time. In Debian 9 I instaled octoprnit. In Debian it wasen.t easly either because I had small problem in install python. I'm glad you made it.
