Unable to Compile Example code.

[teezzan]

Hello, Thanks for the awesome job that you have done.

I am unable to compile the mouse example code. I got this error

Error compiling for board ESP32S2 Dev Module.

What am I doing wrong?

My version of arduino-esp32 is 2.00-alpha. I hope that isnt the cause of the problem? Thank You.

Best Regards, Taiwo

I dont remember now, but most likely HID is broken in arduino-esp32 v2.0.0

Hello! I have the same problem with MSC example, it didn't compile with ESP32S2 Dev mod, what I do wrong? Core of ESP32 Arduino IDE is 2.00 Alpha.

[JimDrewGH]

You guys will need the special v1.21 version that @chegewara made for me that works with the alpha version.

[teezzan]

@JimDrewGH How can I get that?

[josjkasan]

@JimDrewGH, you mean to use this libray from 1.2.1 branch? Or this special version somewhere else?

[josjkasan]

Great, I just use this library version 1.2.1 and it works for me. Thanks for library and support!
