这样算枚举成功了吗
我用UsbView查看了一下,收到的信息为
Device Descriptor: bcdUSB: 0x0100 bDeviceClass: 0xDC bDeviceSubClass: 0x00 bDeviceProtocol: 0x00 bMaxPacketSize0: 0x10 (16) idVendor: 0x0471 (Philips) idProduct: 0x0888 bcdDevice: 0x0100 iManufacturer: 0x00 iProduct: 0x00 iSerialNumber: 0x00 bNumConfigurations: 0x01 ConnectionStatus: DeviceConnected Current Config Value: 0x00 Device Bus Speed: Full Device Address: 0x02 Open Pipes: 0 最后这一个是不是不对? 我用DriverWorks生成了一个测试文件,它有错误如下: ERROR opening device: (0) returned from CreateFile 请高手指点一下,在设备做好了上面的枚举后,怎么开发驱动? |
