Cannot bring device up -- Operation not permitted

[chytzkoi]

Hi,

I have an issue with specific device 7392:a812 Edimax Technology Co., Ltd Edimax AC600 USB. Firstly noticed on my router which is running Gentoo linux and there I have already running for two months the 0bda:8812 Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac 2T2R DB WLAN Adapter. I plugged the Edimax one and it refused to be brought up. So I plugged in my debian laptop cloned the repo fresh and installed the module with same results. Is there anything else which I would be able to try to find the issue?

I have attached
rtl8812au_edimax_issue_01.txt
detailed info. Basically it boils down to this

#ip link set up dev wlx00e04c1cd536

Are you sure you have the right command there?

I thought it was something like

ip link set wlx00e04c1cd536 up

Anyways it all should work, according to other users.
