# Summary
Startech 116U-USBC-DOCK is not recognized when connected (over USB-C).
Power delivery system is working partially.
# Expected Behaviour
The attached dock, its connected USB ports and displays should be
recognized and be usable.
# Actual Behaviour
The device is not recognized, no relevant messages are visible in the
kernel log when the device is connected.The following messages are
present in the kernel log (there are no thunderbolt or usb messages):
```
