New on this forum but already a happy teensy user.
I'm looking for a solution to use usb and serial1 communication with only the usb cable. This is to switch easily between devices, other teensy with xbee, Android or pc. I've came to a solution to use a usb3 cable and connect tx/rx to the high-speed wiring from the usb3 and use the rest as standard (D+ D-). On the second teensy same connection, so no problem. I'm wondering if connecting to, let say, a pc usb3 port would be harmful for either teensy or pc (for this device the communication goes through D+ D-)? Thanks in advance for the support.
