Output of cat /sys/kernel/debug/usb/usbmon/2u
I can reproduce the same problem on 5.5.2 and 5.4.3 as well.
When connecting Yi 4K+ camera to USB port on Thinkpad T495 I get following error:
[ 6376.553655] usb usb2-port3: Cannot enable. Maybe the USB cable is bad? [ 6377.441641] usb usb2-port3: Cannot enable. Maybe the USB cable is bad?

There is no problem when connecting other devices to the USB ports, there is no problem when I connect the camera to USB ports on dock station. If I try to connect the camera to the laptop via USB-C nothing happens.
The camera works fine when connected to other PCs too (Thinkpad T420 running Ubuntu 14.04 and another PC with Windows 7).
I am attaching output of cat /sys/kernel/debug/usb/usbmon/2u when connecting the camera ot the USB port (file "usbmon_fail").
Hope this helps, I'm happy to provide further assistance in debugging.

Good (dockstation port) usbmon
I am also adding output of cat /sys/kernel/debug/usb/usbmon/2u when the camera is connect to an usb port on the dock station - no problem here, everything works fine.

--- Comment #2 from Lukas Vacek ([email protected]) --- I can confirm the same problem with another Yi 4k+ (using many different cables) so it's not a hardware issue.
