--- Comment #21 from Tomasz Duda <tomasz.m.duda@gmail.com> ---
Hello,

FWIW I'm experiencing the same problem with Lenovo Powered USB-C Travel Hub
(model: L01UD027-CS-H, P/N: 4X90S92381): the interface is going up and down.

I'm running FreeBSD 13.2. I've patched "if_ure.c" to recognize this hub, I set
"hw.usb.ure.debug" to "1", but there is nothing beside:

    ue0: link state changed to DOWN
    ue0: link state changed to UP

in dmesg.

Anything I can try to workaround (or pinpoint) this bug?
