是否有 API 调用来启动硬件设备扫描 [英] Is there an API call to start a scan for hardware devices

问题描述

关于这个问题，但是... 是否可以通过 API 触发新的硬件设备扫描?我有一个串行端口蓝牙设备，我通过 API 调用与 32feet.net .NET 自动配对蓝牙，效果很好.虽然我可以在扫描设备时查询串行服务，但 COM 端口没有显示在蓝牙设备对话框的 COM 端口选项卡中.

Related to this question, but... is it possible to trigger via API a new hardware device scan? I have a serial port Bluetooth device that I'm pairing automatically via API calls with 32feet.net .NET Bluetooth, which works quite nicely. While i can query for the serial services in the scanning of the device, the COM ports don't show up in the Bluetooth Devices dialog's COM Ports tab.

我的回答:

强制'扫描硬件更改结帐 "如何强制从一个设备树重新枚举应用程序" 示例在那里显示如何强制整棵树重新列举.

To force the 'scan for hardware changes' checkout "How To Force Reenumeration of a Device Tree From an Application" the sample there shows how to force the entire tree to be re-enumerated.
