Driver for Arduino to access USB Device?

Hello,

I'm trying to connect a USB device serially (Serial1, Pin 1 and Pin 0). The Arduino is the host. Unfortunately it doesn't work at the moment. I suspect because the device requires a driver on the PC, among other things. For Linux I found the following: https://patchwork.kernel.org/project/linux-usb/patch/20190107073149.8214-1-max.schulze@posteo.de/

How is this with Arduino? Maybe I'm searching wrong and that's why I can't find an answer.

Thanks!
Andy

Hi and thanks!

Everywhere it is advertised and said that R4 can also host. Have I really been deceived? A pity...

Thank you for your explanation and help.
