I hope somebody might be able to help me start this project.
At a top level I want to use CAT control for a Ham Radio. This is already solved for a serial connection to the radio or using a serial to USB converter.
My use case requires a USB host connection to the radio which acts as a peripheral device. In Linux I can see the host exchanging addresses, speed and then transferring data to and from a connection. In windows it is seen as a COM port.
I understand I will probably need to use the USB Host library and develop a suitable controller that suits the radios interface. Since its a "simple" send and receive operation and has little intelligence the issue seems to be negotiating the type of interface (speed and address?).
I am using the Arduino Zero because it seems to work well for USB host development. I did a simpler project a couple of years ago for a gaming spinner as tunning control. Fortunately, this device was recognized by the Joystick example, and I customized the parsing.
This new project is not so simple, I need help understanding USB Host better, creating a development environment to see how and capture the initial handshake sequence.
Anybody already knows of this type of USB device or experience writing for custom USB devices.
