Error: can't use storage command in MessageContent with interface 0; interface class is 255, expected 8. Abort

I can use it but usually with troubles

S.O: Manjaro
chipset: RTL8811CU

Similar - usb mdoeswitch didn't work, i went ahead and built the driver, and installed it - wifi sprang into life

[kulkravi]

I cloned, rebuilt the driver and installed. Still didn't work.

Hi there, people. I was experiencing the same problem (the exact same problem), and I was capable to solve following these instructions:
https://askubuntu.com/questions/1162974/wireless-usb-adapter-0bdac811-realtek-semiconductor-corp

follows:

sudo apt update
sudo apt install build-essential git dkms
git clone https://github.com/brektrou/rtl8821CU.git
cd rtl8821CU
chmod +x dkms-install.sh
sudo ./dkms-install.sh

sudo modprobe 8821cu

I expect to help because it's cost my entire night, and this solves my problem.

@wdvictor
I was used the same instructions to install in my machine, but the adapter is not recognized
