在LPC1769微控制器中具有批量传输的USB供应商特定类
我正在尝试在LPC1769微控制器中实现USB供应商特定类的批量传输。 我有一个USB生物识别模块，提取了它的设备信息。因此，我配置了以下描述符在LPC1769微控制器中具有批量传输的USB供应商特定类,c,usb,microcontroller,nxp-microcontroller,C,Usb,Microcontroller,Nxp Microcontroller,我正在尝试在LPC1769微控制器中实现USB供应商特定类的批量传输。 我有一个USB生物识别模块，提取了它的设备信息。因此，我配置了以下描述符 const uint8_t USB_DeviceDescriptor[]={}; const uint8_t USB_ConfigDescriptor[]={}; const uint8_t USB_StringDescriptor[]={}; 现在，我的USB生物识别设备和我的LPC1769设备具有类似类型的设备信息 （我已经在我的Ubuntu P

要操作“供应商特定”类USB设备，您可以使用特定的内核驱动程序或/WinUSB作为驱动程序与用户模式应用程序一起使用。每当没有为特定USB设备（VID和PID）安装驱动程序时，它将显示“？其他设备” 在设备管理器中。但是，在我的案例中，它被列在“通信设备类”下，尽管我已经 将我的USB类协议更改为“供应商特定类”。为什么？驱动程序实例正在尝试与 相同的视频和PID。我已将我的设备更改为USB生物测量设备。它表现在“宇宙”中 串行总线控制器列表” 现在，您可以将其与“Android Studio平台”的Android选项卡集成。有一个API称为“UsbManager”
感谢您的参与。非常感谢。在更改了与USB设备类似的VID/PID后，我将设备放入“通用串行总线”列表中。我忘了以前我已经安装了驱动程序。我正在按照你的建议尝试LibUSB。您能告诉我如何从PC端将数据发送和接收到USB设备吗？
