Using one USB cable for 2 devices

Friday, February 21st 2025, 1:27am

Hi all,

I am making custom XLR 5 pin cable, which will feed Octo with power and singal. I am wondering if it is possible to splice the singal wires so I can connect the HFN to?

In essence that would mean that I have one USB cable 2 devices.

Thank you.

I don't think so. A USB2.0 port has +5V, Ground, Data (+) and Data (-). USB is a Host-Device Protocol and each USB device requires it's own data lines. To connect 2 x USB devices you need +5V, Ground, Data (+), and Data (-) for each device, so a minimum of 6 pins. You could connect a small 2-port USB hub located near the Oct and HFN, then plug each one into a port on the USB hub. Here is the pinout of a 10-pin USB2.0 Header.
