Position does not change, in the case, by the object of all of the port before the physical interface position of port each after jump and jump
Reason interface position is successively matched, physical interface position and after the jump physical interface position consistency before jump, then
Both think to belong to same external equipment, so as to the new corresponding relationship of port and equipment after jump:
The after the jump new port 1 port COM44 of equipment is COM69；
The after the jump new port 2 port COM53 of equipment is COM28.
It need to understand, device port method of determination provided in this embodiment is solved according to the constant characteristic in physical interface position
Certainly the problem of port-hopping, namely before port jumps the physical interface position of each equipment is saved.Once end
Mouth jumps, so that it may obtain the physical interface position of new port after all jumps, and the object with each port before jump one by one
Reason interface position is matched, as long as the new physical interface position of port and the physical interface position consistency of old port, can sentence
Both fixed is the same equipment.Said physical interface position is consistent, refer to PCIROOT (0)/PCI (27CC)/USBROOT (0)/
This part physical position consistency of USB (2) or PCIROOT (0)/PCI (27CC)/USBROOT (0)/USB (1), which being capable of body
The position for revealing USB physical interface is believed that as long as the position consistency of this part physical interface of jump front and back and belongs to same set
It is standby.The part and do not include port position including, since port position can jump, the physical interface comprising port position
It is different always before and after position hopping.
The problem of device port provided through this embodiment determines method, can efficiently solve port-hopping determines
The corresponding new port of equipment promotes the usage experience of user to complete the data communication of terminal and equipment after item becomes.
