I'm building in robotics. Setting up a new 3d camera today. I found that the 10m active USB C cable that I bought transfers power in both directions, but only transfers data in one direction, it turns out to be some weird video USB variant. Next I needed to plug a gripper into a modbus controller. That uses an M8 8-pole 20cm cable. The controller manufacturer recently decided to switch from male to female connector, so now the cable needs to be male-male. After searching online for hours, I believe that is impossible to find as everyone only sells male-female cables. I'm continuously surprised by how difficult it is to plug things together and how non-descriptive cable "standards" are about the actual capabilities of cables and connectors.
