I looked all over the internet and found that there was no project out there that converted the USB from a USB Mouse/Keyboard, sent the signals to the ESP32, processed them, and transferred the signals to the Windows computer to act as HID input. Is there any code that does this, and...
I'm currently building a USB keyboard using the ESP32-S3 and when upgrading to the latest Arduino Core (3.0.0-3.0.4), the reporting of LEDs (Caps Lock, Num Lock, etc.) did not happen anymore, even though the typing works. Downgrading to 2.0.13 makes the code work again. I attached...

I need to have the ESP32-S3 act as a USB host so I can plug a keyboard into it. Thus far I have not been able to find out any information on how to do this. Would someone please point me in the right direction. The examples are quite limited for host applications. ...
So I have an idea for a project that involves using the ESP32 as both a USB storage device and a bluetooth keyboard/mouse combination. I've been able to find documentation for how to use an SD breakout board to read and write to and SD card and I can use a male USB type A to ...

It basicaly acts as a USB HID Device sending Keyboard characters. GND VCC D- D+ are connected via AWG24 Tefzel cable to a USB Screw Terminal. Version 1: 50cm cable, No problem, everything works fine continuesly! Version 2: Using 150cm cable. initially everything works fine for 30-...
