How to add an input endpoint to STM32L4R52 [Copy link]

I refer to Quanquan's book and want to implement a USB keyboard with mouse function (method 2), which requires adding an endpoint 2.

I don't know what to do, and I've looked up a lot of information online but it doesn't help.

Please give me some advice, thank you!

I find you don't understand what this has to do with circuit layout. You probably haven't read the book on circles.

This only has to do with the USB program, the buttons are just normal buttons.
