Wiring a USB-C (host) cable question
If you want the cable to act as Type-C host to mini-B plug (to plug into a device with mini-B receptacle), you should connect A5 pin to ground via 5.1k 5% resistor inside the Type-C overmold. This will inform the Type-C host that the cable is "a device". Although the mini-B is not in the official list of allowable cables in Type-C specifications, you can use the wiring schema for Typ-C to micro-B plug, it is there, and mini-B is one-to-one wired to micro-B.
