           Summary: usb on Dell WD19TB Thunderbolt Dock stop working
           Product: Drivers
           Version: 2.5
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: USB
          Assignee: drivers_usb@kernel-bugs.kernel.org
          Reporter: maggu2810@gmail.com

USB is working on my Dell WD19TB Thunderbolt Dock with Fedora kernel build
6.10.0-64.fc41.x86_64

It does not work with 6.11.0-0.rc4.38.fc41.x86_64 anymore.

Here is the kernel log after plug-in it while the system is running:
