I already turned pi zero as HID device(slave), after connect to PC(host) by micro USB port with a normal Type-A to micro cable, Host can Identify as a HID and avaliable to trans keyboard message.
now I need to connect an another USB UVC device to pi zero because I want generate some message from image to send out through HID.
(I know there have a PICam, but not suite me.)
But I have no addational USB port to use…
I tried use a org cable (micro-M to A-F) and USB hub to extend USB port, but HID function invalid.
1. Is HID function can normally use through a Hub?
2. or there have another method to connect another USB device when pi zero is turned to HID device?
