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.
