--- Comment #10 from Niko (nrkowalski@gmail.com) ---
Yep, all resolutions and framerates are there and appear to be working. I just
noticed there is a different PID when its detected as SuperSpeed (0x009c) vs
SuperSpeed Plus (0x009b).
I guess thats how it changes what is supported based on connected speed.
Anyways whats weird ( or not weird ) is that its now working at the 10Gbps
speed when using USB4.
Here is the output of 'lsusb -d 0fd9:009b -v', Do you want me to boot into an
unpatched kernel so I can do the same for the other PID (0x009c)?
