Is your feature request related to a problem?

I am trying to enumerate the device using the arduino Dual Role device_info example. Here is the descriptor info that I pulled off using a computer:

Describe the solution you'd like

I would like it supported so I can connect tor RS-232 devices using the USB Host.

I have checked existing issues, dicussion and documentation

@makermelissa what is your setup, I think this should be already supported. If you are using Arduino IDE, please try DualRole/CDC/serial_host_bridge, you can jumper wire tx <-> rx on the ftdi and that would echo back anything you type in arduino monitor. Let me know if it does not work for you, I will pull out a similar hw to test with and/or update tinyusb (core/arduino lib) if needed.

[makermelissa]

I'll give that a try. Setup is just a feather rp2040 with usb host using arduino. I did have it work with some other devices like a mouse and 3D printer.

[makermelissa]

Nothing is echoing back.

[hathach]

@makermelissa ok, I will pull out the hw to test and post updat here.

Update: I think I reproduce the issue, working on the fix :)

@makermelissa https://github.com/adafruit/Adafruit_TinyUSB_Arduino/pull/551 pull the latest from tinyusb, this should fix the issue with ftdi driver. Please give it a try and let me know if that works for you.

@makermelissa let me know if you need any help to test this out.
