Subject: Re: rt8000usb driver issue (maybe interaction with other drivers)

Hello Bagas,

The distro I am using is:
Jetson Linux 35.4.1 which is is part of JetPack 5.1.2

Supported Linux Kernel version: 5.10 LTS
aarch64
sample root fs built from: Ubuntu 20.04

When I asked Nvidia directly, their response was "Most likely it could
be wifi driver issue because it gives."

These are the drivers being loaded:

rt2800usb              36864  0
rt2x00usb              24576  1 rt2800usb
rt2800lib             122880  1 rt2800usb
rt2x00lib              77824  3 rt2800usb,rt2x00usb,rt2800lib
mac80211              811008  3 rt2x00lib,rt2x00usb,rt2800lib
cfg80211              724992  2 rt2x00lib,mac80211

I've not worked with driver code before, so I am out of my element
here.  I saw in the git history for rt2800usb some changes went in
since I was using the USB wifi adapter on an older system that has a
linux version older than 2019 (when the OS was compiled and flashed on
the machine).

And maybe something else is broken somewhere.  Just not sure how to
help figure out where this is all broken.
