Hey! 1. The cables have a "twist" internally so they electrically match if you if you attempt to "loopback". They'll also have custom branding on the ends to make it clear they are not USB cables. 2. The modules/dock/cables are electrically compatible with USB (5V power, 3V3 data) and won't cause any damage to a USB device. The reason we selected those connectors is because they are rated for many insertions, relatively cheap and easy to get assembled as proper moulded cables, SMT placeable, and strong. We did evaluate many options but nothing came close to the quality at a reasonable price. Hope that answers your question!
