Compile fails if using usb libraries because of HIDTypes.h:

[psxde]

Hi,

if I use NimBLE instead of the standard BLE stack together with USB Host, I get compile errors like that:

Compiling .pio\build\esp32-s3-devkitc-1\lib3e1\NimBLE-Arduino\NimBLEClient.cpp.o

Thanks, I will look to change these.

@h2zero Building with platformio for ESP32 S3 platform and the following versionned library deps (with USB Host), the same build failure appears.

Adafruit TinyUSB Library has also a symbol HID_SUBCLASS_NONE.

NimBLE's HID_SUBCLASS_NONE is used in TinyUSB's symbol declaration. Hence the "expected identifier before" error .

Workaround: Both library may be imported in different translation unit to avoid symbol/macro conflict.

@davidandreoletti If you could please check that this is resolved by #757 I will merge it
