To be various types of USB ports such as USB 1.0, USB 2.0, USB 3.0 or USB Type-C.
As shown in Figure 1, the parameter regulation means of the embodiment of the present invention may comprise steps of:
Step 101, the parameter information for obtaining target packet, target packet are to be set by USB port in the first communication
The standby data packet transmitted between the second communication equipment.
When specific implementation, target packet at least may include following two form of expression:
The form of expression one, target packet may include: that the first communication equipment is sent out by USB port to the second communication equipment
The first data packet sent and the first communication equipment are based on the first data packet by the second communication equipment by the way that USB port is received
Second data packet of passback.
Herein, the second communication equipment can be such that based on the process of first the second data packet of data packet back firstly, second
Communication equipment demodulates the first data packet received, then the obtained data of demodulation are intactly packaged, and obtains the
Two data packets, then the second data packet is sent to the first communication equipment.
The form of expression two, target packet can be the first communication equipment and sent by USB port to the second communication equipment
Data packet, or, the first communication equipment pass through the received number sent from the second communication equipment to the first communication equipment of USB port
According to packet.
In embodiments of the present invention, parameter information can be determined based on the specific manifestation form of target packet, specifically
It is bright as follows:
For the target packet of the above-mentioned form of expression one, parameter information may include: the data and the of the first data packet
The data of two data packets.
Herein, the data of the first data packet can be the first communication equipment to the second communication equipment send the first data packet it

Step 102, the parameter information according to target packet, obtain target value, and target value is used to characterize the biography of USB port
The superiority and inferiority degree of transmission quality.
In embodiments of the present invention, above-mentioned target value can be determined based on parameter information, be described as follows:
It include: the situation of the data of the first data packet Yu the data of the second data packet for parameter information, target value can be with
It is poor data transmission error rate.Herein, poor data transmission error rate can be the bit error rate (bit error rate is referred to as symbol error rate),
Word error probability or block-error probability etc..
It include: the data volume of target packet and the situation of transmission duration for parameter information, target value can be data
Transmission rate.
Step 103, according to the comparison result of target value and preset value, adjust the driving parameter of USB port.
By foregoing teachings it is found that the driving parameter of USB port influences USB eye diagram quality, thus by adjusting USB port
Driving parameter can be realized the adjustment to the transmission quality of USB, that is to say, that the driving parameter for adjusting USB port can make
Target value is stated to change.
It should be noted that in practical applications, it can be by adjusting the driving parameter of USB port, so that target value connects
Nearly preset value can specifically determine, the embodiment of the present invention is to this according to actual needs alternatively, making target value equal with preset value
It is not construed as limiting.
The driving parameter of above-mentioned USB port at least may include following one: the driving voltage of USB port, USB port
Driving current, the rising edge of signal, signal failing edge.
In embodiments of the present invention, by the parameter information for the data packet transmitted between two communication equipments of acquisition, and according to
Parameter information obtains the target value of the superiority and inferiority degree of the transmission quality of characterization USB port, further according to the ratio of target value and preset value
Compared with as a result, the driving parameter of USB port is adjusted, so that the driving parameter of USB port can be according to different transmission qualities
Situation is automatically adjusted.In this way, the driving parameter of USB port is enabled to be carried out certainly according to connecting line/device of different performance
Adjustment is adapted to, so as to make communication equipment both adapt to original-pack connecting line/device, also adapts to non-original-pack connecting line/device,
The compatibility of the USB port of communication equipment can be made more preferable.
In embodiments of the present invention, above-mentioned steps 102 and step 103 can be based on the specific manifestation forms of target packet
It determines, is described as follows:

Under poor data transmission error rate and the unequal situation of default error rate, the driving voltage of USB port is adjusted.
Herein, illustratively illustrate the acquisition modes of above-mentioned poor data transmission error rate: using poor data transmission error rate as error code
For this application scenarios of rate, if the data of the first data packet are " 101011 ", the data of the second data packet are " 101010 ", then
After comparing, it is not difficult to find out that the last a data of the second data packet is different from the last a data of the first data packet, at this time
It is considered that poor data transmission error rate is 16.7%.
Above-mentioned default error rate, which can according to need, to be set, for example, default error rate can for 0,1%, 10% or
Person's other values.
Above-mentioned poor data transmission error rate and the unequal situation of default error rate at least may include: poor data transmission error rate
