I am working on an Arcade Stick/Fight Stick enclosure. Internally, the PCB (Brook UFB) runs USB over a standard Ethernet cable, to a Neutrik RJ45 passthrough. I typically then create an RJ45 to USB A cable to use the Arcade Stick on my PC, and I have never had any issues with this in previous builds.
I decided I wanted the convenience of the symmetrical USB C connector. I purchased a USB A to USB C cable, cutoff the USB A end, and wired it to the RJ45. This particular cable has only Red (VCC), Black (GND), Green and White (D-/D+) conductors. After plugging the cable in to my PC's USB C port, the PCB does not power up. When I plug the cable into a USB A port using a USB C to USB A adapter, everything works just fine. What might be going on here? Thanks for any insight you can provide.
For reference, the Brook PCB RJ45 USB pinout is below.
