In an embodiment of the present invention, as shown in FIG. 3, the request packet 4G is composed of 8 bytes (8 Bytes), and includes five sheds. The bits are respectively - the first block 41. The second stop 42, the third hold, the fourth stop 44, and the fifth stop 45. The first block 41 can also be called a type buff (bmReqUestType), and a bit group is used. The first block 41 is available for storing a bit map (Bit-Map) for recording the request packet 4Q. The device information of the type can be used to touch the characteristics of various request commands, and can transfer the transmission direction when transmitting data, and the bit map contains 8 bits: (Bit), and the state of Binary It is said that the 8 bits > yuan is divided into three health rooms, and the towel is used as the first bit. When the value is used, the system is used to indicate that the request packet is not required. (as shown in Figure 1) is sent to the external electronic device; conversely, when the value is 1, it indicates that the request packet 4 is transmitted by the external electronic device to the 5H computer system 20; The second interval uses two bits, which is used to indicate the transmission type sorrow. When the value is 〇, it means the standard, when its 'no grade, when its value is 2, it means the supplier, when its value is 3 , which means that the other is used to define the device level and the placement of the supplier, etc., and the third section makes Five bits, used to indicate the receiver, when its value is 〇N*, means the device, when its value is 1, it means the interface, when its value is 2 Ν ', the table is not the endpoint, when its value is 3 When it is the other, the rest are not used (or reserved); the first field 42 of the shai can also be called the request block (bReqUest), using a byte, which can be used to store the value, the values are 〇 to 丨 2, where the value 0 represents the acquisition status (GET_STATUS), the value 1 represents the clear feature (CLEAR-FEATURE), the value 2 represents the reservation, and the value 3 represents the set feature (SET-FEATURE) 'value 4 represents Reserved, the value 5 represents the setting address (SET_ADDRESS), and the value 6 represents the acquisition description element (Get_Descriptor) 'Value 7 represents the setting description element (SET_

Please refer to FIG. 4, the response packet 5 is composed of one byte, and includes nine _ bits, a sub-response-response shed 5, a second response block 52, and a third response block. Bit 53, fourth response booth 54, fifth response field 55, sixth response block, seventh response pad 57, eighth response field 58 and ninth response block 59. The first-response block 51 may also be referred to as a bit length (bLength), using a byte to record the length of the byte of the response packet (or device description element); The second response block 52 may also be referred to as a device description metablock (bDescriptorType) 'using a byte to record the response packet 50 (or device description element) type; the third response block 53 may also be called a specification Field (_SB), use, a byte to store the transmission specification (or version) of the external electronic device, for example: USB version 1.1 or 2. 〇 version; § 希弟四 response block 54 It can also be used to support the device level (bDeViceClass), using a byte to store the characteristics of the device level of the sub-device; > 1307017 δ海苐5 response block 55 can also be called as sub-level code booth (10), eSubClass ), using a byte for storing the transfer of the external electronic device, and distributing the data allocated by the rotary electronic device and cooperating with the data stored by the third wireless device, the fourth response block When the 54 is reset to 〇, the fifth response block 55 is also heavy. If the fourth response block 54 is not set to Yang instant, the fifth response block 55 is reserved for the external electronic device to perform the allocation; the sixth response block 56 can also be called the communication protocol code block. (bDeViceProtocol), using a byte for storing the communication age code of the external electronic device 'The communication protocol code system _ the external electronic device is assigned' and the fourth response block 54 and the fifth response shed The data stored in bit 55 is set, and if the money sub-device can be assigned a device level, the view protocol of the external f-sub-device is based on the external electronic device instead of the track protocol of the transmission mode. Basically, in addition, when the value of the sixth response field 56_store is reset to 〇, the external electronic device will not use the preset communication protocol, and vice versa, when the sixth response block 56 is set For xFF, the external electronic device can use the preset communication protocol; the seventh response block 57 can also be called the maximum packet size block (bMaxPacketSizeO) 'Use a byte to record in different transmissions At speed, Respond to the maximum size of the packet 5; 5 Hai eighth response block 58 can also be called configuration block (bNumConfigurations) 'Use a byte to record the number 1307017 value to correspond to other speed settings; and the ninth response Block 59 can also be called a reserved field (bReserved) 'Use a byte, which is used as a reserved pin and is unused.
