General issue report

I have a 3D printer that exposes serial over USB. Can I use this library to read that data if printer is connected to an ESP S3's host mode port?

Hello @khayamgondal , yes, we have support for USB Host serial.

Here are some examples, that can help you started: https://github.com/espressif/esp-idf/tree/master/examples/peripherals/usb/host/cdc

But the chances are that you will need to implement a device driver specific for your device.

Could you please share USB descriptors of you 3D printer? You can find them by connecting the printer to PC and then lsusb -v on linux, or using USB Device Tree Viewer on windows
