Hi,Thank you, we've solve the issue by add resistors.And it works with nex Mac pro type-c now.

I'm looking forward to hearing about your findings.This is good work here. Thank you sennin. Just to add some info, the following application note might be helpful. I know it deals with a different microcontroller, but it describes in general what is required for a legacy USB device in terms of the resistors on the CC lines when using a USB Type-C connector. In particular, there's a schematic on pg. 16 that might help.http://www.st.com/resource/en/application_note/dm00235987.pdfHi,Thank you, we've solve the issue by add resistors.And it works with nex Mac pro type-c now.

Is 1.5--1--1.5--3--3--1.5--1--1--1.5 supported?The link with all supported layouts says it is, but looking at the photo of the PCB, I can't spot the corresponding switch / stabilizer holes.
Did you measure it?
Hi,Guys we've sent all the orders except 3.They didn't reply me about the color issue (We miscalculate the color, so black one is not enough )If you guys haven't received your pcb, please tell me
