I have a pi 3 running Win10 IoT and 3 arduino pro mircos connected via usb. When I try to search via VID & PID for the arduinos I get back nothing:
var aqs = UsbDevice.GetDeviceSelector(vid, pid); var arduinoDevices = await DeviceInformation.FindAllAsync(aqs); //arduinoDevices contains 0 objects
However if I get all devices then search for ones with "Arduino" in the name I can find them. I actually get 6 back.
var devices = await DeviceInformation.FindAllAsync(); var arduinoDevices = devices.Where(x => x.Name.StartsWith("Arduino")).ToArray(); //arduinoDevices contains 6 objects
I'm guessing for each physical device there is an entry for accessing the board and another for accessing the bootloader. Is this correct? How do I know which is which?
The weird thing is when I look at the VID & PID from the 6 objects they show the same values I was searching for using the first block of code above. Is this a bug in Windows IoT, the Arduino, or am I doing something wrong?
If I search by VID & PID for other USB devices I can find them so I'm leaning towards it being something specific with the Arduino. On the default Win10 IoT dashboard I can see my 3 arduinos listed under "Connected devices" which leads me to believe there is a way to get the device entries I am looking for.
