Ok so I have the USB Host shield running OK and I can extract the device descriptor information (see attached file). This is using the USB_Desc example from the Host Shield Library.
However I have tried all the various example terminal emulation code and cannot get anything to read the data that is being sent every second. I can see the data when the USB device is plugged into a PC.
Doing a bit of searching I can see the USB device is showing up as a FTDI Bridge (I2C/SPI/UART/FIFO).
The MK3 USB device is a Victron interface unit between their inverters internal bus and USB.
Not sure where to go now for further help. I just need to be able to send USB commands and read USB data back.
