FTDI #116

Closed z0rbal closed 6 years ago

Hi, I've been using two FT232s thru android OTG (with hub) with your code to connect to some dedicated hardware (NMEA on port1 and my own hardware on port2) - it's working great. However I want to use the dual FT2232H device (so there's no hub) - it reports as having two interfaces - but I guess your lib doesn't handle it - any idea how to do it? Also is there a callback for writebuffer remaining or a count of characters sent or even just string sent complete? Thanks.

You just need to enumerate the interfaces on the usb device and pass the interface index into the specialised createUsbSerialDevicefunction that accepts an extra parameter - UsbSerialDevice.createUsbSerialDevice(device, connection, usbInterface);

Thanks Bill - I knew I was missing something - I'll give it a go!
