[UWP] ClaimedBarcodeScanner调用StartSoftwareTriggerAsync突然抛出一个异常 [英] [UWP]ClaimedBarcodeScanner call to StartSoftwareTriggerAsync throws an exception all of sudden

问题描述

使用标准BarcodeScanner样本一直在使用UWP条形码扫描应用程序。在Win10桌面上做dev，使用网络摄像头一切正常。预览工作和条形码检测非常快速和准确。然后开始使用Win 10周年纪念版测试Lumia
640。它工作了几天，虽然预览不起作用。试图开始预览说它失败了"没有足够的资源"。在错误事件中。无论如何 - 它仍然如此快速和准确，即使没有相机预览也可以使用
。 将手机放在任何地方近距离阅读好的代码。 正在研究一些UI方面，突然在调用脚趾StartSoftwareAsync调用上获得异常。抛出和异常："连接到系统的设备
无法运行。 （HRESULT异常：0x8007001F）"。 已多次检查所有内容，重新启动手机，卸载应用程序，清理项目，重建所有内容 - 每次都一样。 也许是最近的手机更新？ 
此时可能导致此错误的其他任何想法？ 一些记录或方式来获得更多关于什么特别不满意的信息？

Have been working on a UWP barcode scanning app using the standard BarcodeScanner sample. Doing dev on a Win10 desktop, all works well using the webcam. Preview works and barcode detection is amazingly fast and accurate. Then started testing on a Lumia 640 with Win 10 Anniversary Edition. It worked for a few days, although the preview does not work. Trying to start the preview says it fails with "not enough resources" in the on error event. Whatever - it is still so quick and accurate that it can be used even without the camera preview.  Point the phone anywhere close read a good code.  Was working on some UI aspects and all of a sudden getting exceptions on the call toe StartSoftwareAsync call. It throws and exception with: "A device attached to the system is not functioning. (Exception from HRESULT: 0x8007001F)".  Have checked everything many times, restarted the phone, uninstalled the app, clean the project, rebuild all - same thing every time.  Maybe a recent phone update?  Any other ideas of things that might cause this error at that point?  Some log or way to get more information about what in particular is unhappy?
