How to use HIDAPI to communicate with rp2040 keyboard and mouse composite device on the pc to control keyboard and mouse actions

[941597815]

I saw the keyboard and mouse device example in Adafruit_TinyUSB_Arduino\examples\HID\hid_composite and I want to send control commands through HIDAPI on the PC to perform keyboard and mouse actions. How can I do it?
I use hidapi in python to send commands, but I don't know how to receive commands in rp2040

Adafruit TinyUSB has an example sketch for that, alongside with Python and JavaScript test scripts.

Thank you very much for your reply, I have some problems now.

void set_report_callback(uint8_t report_id, hid_report_type_t report_type, uint8_t const *buffer, uint16_t bufsize) { // Serial.printf("SET_CBK: id=%u, len=%u, report_type=%u\n", report_id, bufsize, report_type); if (bufsize == 64) { usb_hid.mouseButtonPress(RID_MOUSE, MOUSE_BUTTON_LEFT); usb_hid.mouseButtonRelease(RID_MOUSE); } usb_hid.sendReport(0, buffer, bufsize); }

I called the left mouse click in the callback function, and it seems that only the mouse lift was performed:
usb_hid.mouseButtonRelease(RID_MOUSE);

What is the reason?

I have no way to reproduce that without the full sketch.
