Here is how i managed to build and install the rtl8188eu wifi driver. It may (or may not) work with you…
You could follow the same path to build and install this GitHub - morrownr/8821cu: Linux Driver for USB WiFi Adapters that are based on the RTL8811CU, RTL8821CU and RTL8731AU Chipsets
It was a bit of pain because you must before build the docker image with the cross-environment which takes a long time
I don’t think my driver could would work for you, but If you want to give it a try, here you can find the module and the fw. Transfer them to the dwarf, copy the fw in /data/firmware and try manually loading the module with insmod (if you don’t know how to do it better don’t try 
)
NOTE: I will not be responsible if this turns your dwarf in a ZOOM G1 or if it steals your girlfriend stratocaster
