USB controller detects the packet transmission situation in the first passage, if non-end of transmission, opens second
Transmission channel, and the remaining packet of first passage simultaneous transmission.
When some queues packets to each USB transmission mouth, open the first transmission channel and the second transmission is logical
Road, first transmission channel and second transmission channel carry out the packet transmission simultaneously.
104th, after the packet end of transmission on each usb data plate, the packet is reassembled as target
Data.
After all packet all end of transmissions, then packet can be recombinated to obtain target data.
The present embodiment also provides USB controller, including：
Split cells, arrangement units, transmission unit and recomposition unit；
It is at least two packets that the split cells, which is used to split data to be transmitted,；
