Thanks for the quick response!

When calling INDATA(), how would you go about catching the incoming data and storing it to something like a byte array, string, binary array, etc.? And am I correct in assuming that the two functions don't need to be called at all?

I also checked out your link, and while it gives a step by step for functions to call, the examples no longer exist, so I will have to do some digging around to find out how these functions actually work, but thank you for this resource!

USB host should be working with arduino, or at least it has been working few months ago.
I even tested now and it is working, with v2.0.3 i think, but im not 100% sure, because i do have few versions installed.

hi, i'm trying to use your example:

https://github.com/chegewara/EspTinyUSB ... s/host/acm, with my esp32-s3-otg-usb. its perfect for my needs. the problem is... i can't get it working. :(

i copied the library to Arduino ide and it compiled and uploaded perfectly, without change!

however, when i run it, your host.init() returns a 1, but the usb_host_install() returns 0. and nothing, like device callbacks work. :(

any thoughts on how to get usb_host_install() working?

thanks 🤓👍

@chegewara, got your ardruino acm-host example working on my esp32-s3-usb-otg board on the usb-host interface with a usb cdc class client dongle plugged into it.

I also have an usb hid class keyboard client working on the usb-client interface plugged into my laptop.

the problem is... only one will work at a time, not both.

to get the usb-client to work, i have to set gpio 18 to:

gpio_set_level((gpio_num_t)18, 0); // USB_SEL: Used to switch the USB interface. When high level, the USB_DEV interface is used. When low level, the USB_HOST interface is used.

to get the usb-host to work, i have to set gpio 18 to:

gpio_set_level((gpio_num_t)18, 1); // USB_SEL: Used to switch the USB interface. When high level, the USB_DEV interface is used. When low level, the USB_HOST interface is used.

Is it possible to get the usb-client and usb-host to work together at the same time?

There is only 1 USB port on esp32 S2/3, so the answer is no, its not possible.

@mistermiser42 were you able to figure it out? I am trying to connect a 3d printer to ESP- S3 and wondering can I use the USB host mode for that
