为什么我的设备显示设备类型是：人体学输入设备
而不是我想要的MASS STORAGE DEVICE 我在INTERFACE DESCRIPTOR中，设置 bInterfaceClass=x08 // bInterfaceClass: MASS STORAGE bInterfaceSubClass=0X04 //bInterfaceSubClass 照理应该PC机识别它为海量存储设备才对啊！ 配置描述符如下： Cfg_Descp[] = { 0x09, // bLength: Size of descriptor 0x02, // bDescriptorType: Configuration CFG_LEN,0x00, // wTotalLength: Cfg+Ifc+Class+Ep = 34 bytes 0x01, // bNumInterfaces: 1 interface 0x01, // bConfigurationValue: 1 0x00, // iConfiguration: none 0xA0, // bmAttributes: bus-powered, remote-wakeup 0x32, // MaxPower: 100mA //--------------------------------------------------------------------------------------------------------------------- // INTERFACE DESCRIPTOR //--------------------------------------------------------------------------------------------------------------------- 0x09, // bLength: Size of descriptor 0x04, // bDescriptorType: Interface 0x00, // bInterfaceNumber: #0 0x00, // bAlternateSetting: #0 0x02, // bNumEndpoints: 2 0x08, // bInterfaceClass: mass storage 0x04, // bInterfaceSubClass: none 0x00, // bInterfaceProtocol: none 0x00, // iInterface: none //--------------------------------------------------------------------------------------------------------------------- // ENDPOINT1 in DESCRIPTOR //--------------------------------------------------------------------------------------------------------------------- 0x07, // bLength: Size of descriptor 0x05, // bDescriptorType: Endpoint 0x81, // bEndpointAddress: IN, EP1 0x02, // bmAttributes: Interrupt EP1_LEN,0x00, // wMaxPacketSize: 0x0A, // bInterval: 10ms //--------------------------------------------------------------------------------------------------------------------- // ENDPOINT2 out DESCRIPTOR //--------------------------------------------------------------------------------------------------------------------- 0x07, 0x05, 0x02, // bEndpointAddress: out, EP2 0x02, // bmAttributes: Interrupt EP2_LEN,0x00, // wMaxPacketSize: 0x0A // bInterval: 10ms }; [编辑 - 6/30/04 by mirror] |
