Error on `usb_modeswitch`: `interface class is 224, expected 8`

[parsanoori]

When I run the following I get:

sudo usb_modeswitch -KW -v 0bda -p c820 -R 

I get:

Take all parameters from the command line

I've got an ezc-5201 wifi dongle. Trying to connect to it via this driver.

had the same issue. I simply built it directly and now it works: after cloning ->

cd rtl8821CU/
chmod +x dkms-install.sh 
sudo ./dkms-install.sh
sudo modprobe 8821cu
