8 years ago It seems like you have found 785 device.
I haven't tried it, but instead of using console.log on the whole DeviceInformationCollection, you can write your own loop walking the collection and look at and output the properties of each DeviceInformation?
https://msdn.microsoft.com/en-us/library/windows/apps/windows.devices.enumeration.deviceinformation.aspx documents the properties it has.
my code: DeviceInformation class
` var uwp=require("uwp");
uwp.projectNamespace("Windows"); var deviceInformation = Windows.Devices.Enumeration.DeviceInformation; var VID=0x10C4; var PID=0x81B9; deviceInformation.findAllAsync().done( function(devices){
console.log(devices); },function(err){ console.log(err); } ); ` result: Windows.Devices.Enumeration.DeviceInformationCollection { '0': Windows.Devices.Enumeration.DeviceInformation {}, '1': Windows.Devices.Enumeration.DeviceInformation {}, '2': Windows.Devices.Enumeration.DeviceInformation {}, '3': Windows.Devices.Enumeration.DeviceInformation {}, .......... '785': Windows.Devices.Enumeration.DeviceInformation {} }
why I can't find any device?
OS: Win 10 Enterprise nodejs: Node.js (Chakra) node@6.0.0
The device can display at Device Manager
