Hi,
I'm new to Teensy, and having 3.2 and 4.1 in my hand.
I'd like to design a device based on Teensy which has capabilities of serial communication along with audio both via USB connection from Raspberry Pi.
I first tried USB Type "Audio", and recognized Teensyduino enables serial communication.
After that I checked my /dev/tty.* (my development env. is OS X), couldn't find corresponding device file, so I guessed that this serial communication is realized via USB HID feature, not CDC.
I came up of two ways to solve the problem:
A: Create new composite device of USB Serial and USB Audio. Reference could be this detailed post that illustrates how to make a new USB device with Teensy.
B: Implement HID serial client for Raspberry Pi (maybe this is not so difficult using high level libusb wrapper like pyusb).
My questions are,
- Is my understading correct?
- Is there any know solution here?
Best regards,
Takashi
