USB Dock Flashes When Connected
So I chose this dock because the Wiki suggested it would work well:

When I plugged it in unpowered, it seemed to work fine.  I got a USB-C to USB-C cable today and plugged it in, and it rapidly turned on and off.  I kept getting messages like:

It just keeps turning the power (and connection) on and off.  I'm on the default Manjaro and the only things plugged into the hub are the power and a USB mouse.  The power appears to work fine alone plugged directly  into the USB-C port, and the hub seems to work fine on my phone.

I'm stuck, any ideas?
