Have you tried both USB connector? There are two.

jep, it's also the one who has power 😅 it's the correct one. I checked

This is not my cup of tea so I am just blindly checking stuff.

Adafruit Feather RP2040 with USB Type A Host

You're probably really used to microcontroller boards with USB, but what about a dev board with two? Two is more than one, so that makes it twice as good! And the Adafruit Feather ...

#

USB Type A connector for USB host capability. D+ on GPIO 16, D- on GPIO 17

#

Maybe the pin numbers matter?

Don't know, but thanks for the hint! I will check if this makes any difference.

somewhere i read that a soft restart does not deinit the usb host so connected devices can still work, but it also said if you would init the usb host with the same pins it would just give back the previous instance and everything would work, strange that the pico feather works with those pins.

#

i would look for examples how others made it to work and try to reproduce the same

#

maybe try a hard reset and see, i don't know what else to try

USB Host support is really early, so feedback is good, and what you want may not work yet.

@rapid rapids that's ok, was worth a try. I will use Arduino for now and try again later. Thanks for your work!
