            Bug ID: 220027
           Summary: USB 3.2 capture cards using incorrect USB speed
           Product: Drivers
           Version: 2.5
          Hardware: AMD
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: USB
          Assignee: drivers_usb@kernel-bugs.kernel.org
          Reporter: nrkowalski@gmail.com
        Regression: No

There seems to be an issue with USB 3.2 capture cards being detected as
SuperSpeed (5Gbps) devices instead of SuperSpeed Plus (10Gbps) which severely
limits their functionality.

This issue has been reported multiple places by multiple people and a similar
bug report with a different capture card can be found here:
https://bugzilla.kernel.org/show_bug.cgi?id=218943

In my particular case I'am using an Elgato 4K X plugged into my PC's USB4 port
which is directly connected to the motherboard. The capture device has been
tested working at full speed in Windows 11.
