Does anyone know what this is?
The releasenotes pdf says it came from Realtek.

What are the roadblocks to getting USB support in the kernel driver?

Is it possible to have a USB part of the driver that uses the kernel 
part of the driver?

The file structure indicates that it is a variation of the USB driver 
from the Realtek group. As such, it will have all the flaws of that 
family of drivers.

That is unfortunate but not surprising.

I have previously estimated that it would take about 6 months of work 
to get such a driver into shape to be submitted into staging. The 
approach taken in https://github.com/neojou/rtw89-usb will take a lot 
less time; however, without the cooperation of Realtek, it will take a 
lot of USB dumps to compare the communication with the chip to 
discover what differences there are between the PCI and USB versions, 
other than the obvious base platform data flow.

Have you tried either the shiqishao or the neojou driver? If you are 
willing to provide me with a device, I could probably give you some 
help getting the neojou driver into kernel shape.

I don't have the adapter but I do want a wifi6 one.
I have a mediatek wifi5 one and that is pretty decent.

It is unlikely the neojou driver with work by replacing the PCI with 
corresponding USB calls?
I tried to compile it (to see if it even compiles :-)) but there are 
tons of "unused-*" warnings.

I've been reading about the lwfinger repo for the rtw89 PCI driver.
I'm guessing at one point the code between neojou and lwfinger was similar?
Do I have this right, the rtw89 driver will compile on ubuntu but not work?
What distro do you use for development?
Maybe Realtek will help to add the USB support. :-)

Can you provide me with a link to a local store that has the DLink 
DWA-X1850?
I'm not opposed to buying you one but it wouldn't be until next year. :-)
