ESP32-S3 - TinyUSB I've just faced a weird situation: an USB Logitech mouse, that fully works when connected to a PC, does not send any byte related to scroll wheel. Input report contains only 3 bytes: 1 for buttons (including the scroll wheel switch), other for horizontal movement and the last for ...

what software are you running on the PC?
how do you tell it which COM port to use?

SW running on PC is proprietary and developed by a third party.

The current way to get the current COM port is referring to the Windows' Device Manager.

when connecting microcontrollers to PCs where the Windows COM port or Linux /dev/ttyUSB* port is unknown I usually have the host software (implemented in C++, C#, Java, etc) cycle thru the connected serial ports transmitting a prompt (e.g. a "?") to each device in turn the target device would be pr...

This COM port number is likely assigned by Windows, exclusively.
I could not find any data structure in TinyUSB that contains an obvious, nor intuitive, reference to this.

If I get you right, it would be enough to receive (part of) descriptor of the current USB devices attached to the PC!
How can I do it?

Hi! My current project ESP32-S3 uses CDC and it's working properly. But the only way to know the number assigned to the COM port (example: COM10) is referring to the device manager, what makes it inconvenient to a remote application that intends to be fully user-independent. So, the question is: is ...

I am developing an ESP32S3-based device that has to be able to host a standard USB keyboard The "usb_host_lib" example (https://github.com/espressif/esp-idf/tree/master/examples/peripherals/usb/host/usb_host_lib/main) works properly to deliver user's keystrokes to the hid host , but does not show ho...

Hi.

Indeed, the ideal would be to program directly the ESP32 components, with no intermediation of a RTOS.

To whom it may interest, a tip on ADC recalibration: I could not find a way to make function "adc_vref_to_gpio" works but I've got other solution to deal with ADC calibration: to edit "vref" field in "esp_adc_cal_characteristics_t" struct, that's the last parameter in function "esp_adc_cal_character...

Hi! I also face a problem related to "adc_vref_to_gpio" function, since it results a error at compile time, although documentation at https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/api-reference/peripherals/adc.html?highlight=adc_power_acquire# "adc2_vref_to_gpio" cause no compile tim...
