Summary:
The USBC Ports on the LG 5K UltraFine fail to start. It doesn't detect that things are connected.

I can't plug a USB mouse into my UltraFine without unplugging and replugging either the mouse into the UltraFine (which is a huge pain in the neck getting behind it), or by unplugging and replugging the USBC connector into my MacBook Pro 2016

Steps to Reproduce:
1. Plug any USBC device into the 5K UltraFine

Expected Results:
1. The device should work like any other USB2 or USB3 device

Actual Results:
1. The device doesn't work
2. The OS doesn't detect it.
3. I can't use the device without unplugging and replugging multiple times

Version:
MacBook Pro 2016 Sierra 10.12.4

Notes:
USBC support on the LG UltraFine is a joke. It's so buggy and doesn't work. This is very frustrating. Did you test this product at all?

Configuration:
5K LG UltraFine and MacBook Pro and USBC Apple cable to lighting + Magic Trackpad, Magic Keyboard, Logitech USB G502 mouse
