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!

Docs is really helpful, worth to read it:

hi, i'm trying to use your example:chegewara wrote: ↑Thu Aug 04, 2022 11:16 pmUSB 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.

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
Re: Getting the USB HOST port on the ESP32-S3-USB-OTG board to work
@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?

Re: Getting the USB HOST port on the ESP32-S3-USB-OTG board to work
There is only 1 USB port on esp32 S2/3, so the answer is no, its not possible.

Re: Getting the USB HOST port on the ESP32-S3-USB-OTG board to work
@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

Let's discuss this in a separate issue:@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
