Description

This issue was found during investigation of this ticket. I've opened this ticket, to clean up the issue tracking.

The issue is, that when sending signals over CDC (serial data) and HID (game controller output) at the same time, at least one of the channels will stall after a while and therefore isn't sending data to the PC anymore.

The steps to reproduce this issue:

1. take ESP32 S2 mini or ESP32 S3 (other boards might behave similar)
2. upload the software with simultaneous CDC and HID output from here
   https://github.com/ChrGri/DIY-Sim-Racing-FFB-Pedal/tree/develop/Validation/Joystick_Serial_test
3. restart the ESP
4. windows game controller output app to check the change in HID output
5. open a serial monitor
6. the ESPs output will stall now after a while, if not, please reduce the delay
   https://github.com/ChrGri/DIY-Sim-Racing-FFB-Pedal/blob/e2798eca295c65b02d2448eeabd65c69a27d08bd/Validation/Joystick_Serial_test/src/Joystick_Serial_test.ino#L54

The expected behaviour is that CDC and HID output streams are stable and don't collapse.

Your Platformio setup is mixing versions. Bad idea. If you want to use core 3.0.4 with Platformio you should consider using pioarduino. https://github.com/pioarduino/platform-espressif32

[ChrGri]

Ideally I would want to use core version 2.x due to library compatibility

[Jason2866]

Development is done with actual core. So if anything is not working with core 2.0.x as wanted/expected it will not be changed/fixed in core 2.0.x.

[ChrGri]

Can you tell me where the versions are mixed?

I've checked the platformio file and it only references espressif32, see

But that's a completely different project!?
So why is CDC + HID stalling with this?

So you are using core 2.0.x. Not core 3.0.4 as you wrote in the issue template.
For core 2.0.x is no development and bug fixing done anymore.

No. The issue happens on core 3 too. Please try the toy example from the top.

We have found a couple problems with the TinyUSB version/commit used within the ESP32 Arduino Core.
There are problems with CDC.

It will take some time to fix. This issue will be kept in the list to be tested.

[SuGlider]

@ChrGri - Could you please test it using Arduino 3.0.0-RC1 version? This uses the last stable TinyUSB version that I have found.

@SuGlider 3.1.0-RC1?

Tried it, but it won't even compile

What am I doing wrong?
