It supports 3 suits endpoint, one control endpoint( endpoint zero) is for bus enumeration, one output endpoint is for Microsoft Windows Vista IR Receiver Emulation Device command and one input endpoint is transmit IR information to host. Endpoint zero is special significance in USB system. It is a control endpoint, and is required by every device. Only control endpoint accept special setup token that the host transfer command to device. During enumeration, host requests GET_DESCRIPTOR to device and device return information (over in endpoint zero) as what device driver top load. The below table is about F71610 descriptor. offset 0 1 2 4 5 6 7 8 10 12 14 15 16 17 Field BLength bDescriptor Type BcdUSB bDeviceClass bDeviceSubClass bDeviceProtocol bMaxPacketSize IdVendor IdProduct BcdDevice Manufacturer IProduct iSerialNumber bNumConfiguration size 1 1 2 1 1 1 1 2 2 2 1 1 1 1 Value 0x12 0x01 0x0200 0x00 0x00 0x00 0x10 0x1934 0x0602 0x0000 0x01 0x02 0x03 0x01 Table 6-1 Device Descriptor offset 0 1 2 4 5 6 7 8 Field BLength bDescriptor Type wTotalLength bNumInterface bConfigurationValue iConfiguration BmAttributes MaxPower size 1 1 2 1 1 1 1 1 Value 0x09 0x02 0x0020 0x01 0x01 0x00 0xa0 0x32 Table 6-2 Configuration Descriptor offset Field size -4- Value Dec., 2007 V0.22P F71610 0 1 2 3 4 5 6 7 8 BLength bDescriptor Type wInterfaceNumber bAlternateSetting bNumEndpoints bInterfaceClass bInterfaceSubClass bInterfaceProtocol IInterface 1 1 1 1 1 1 1 1 1 0x09 0x04 0x00 0x00 0x02 0xff 0xff 0xff 0x00 Table 6-3 Interface Descriptor offset 0 1 2 3 4 6 Field BLength bDescriptor Type bEndpointAddress BmAttributes wMaxPacketSize BInterval size 1 1 1 1 2 1 Value 0x07 0x05 0x81 0x02 0x0010 0x00 Table 6-4 In Endpoint Descriptor offset 0 1 2 3 4 6 Field BLength bDescriptor Type bEndpointAddress BmAttributes wMaxPacketSize BInterval size 1 1 1 1 2 1 Value 0x07 0x05 0x01 0x02 0x0010 0x00 Table 6-5 Out Endpoint Descriptor The string table 1 is about manufacturer information, its’ contents is “FINTEK”, the string table 2 is about Product information, its contents is “eHome Infrared Transceiver.
