Greeting everyone,

I hope everyone reading this is doing very well. 
I have been using two external drives on both of my USB-C / TB3 ports for a while now and one port does not seem to be working anymore.

Both drives are not detected when using THIS port.
One drive has a lamp to show if it even gets power, it is turned off using the port. This lets me think that this is NOT a Windows issue.

I hope someone is able to help me with my problem.

Thank you very much and best wishes
Tim
