Problems solved by technology
[0026] Once the user plugs in the data cable of the first interface connector socket 1a and the data cable of the second interface connector socket 2a at the same time, if the manual interface selection switch 4a is selected to the second interface connector socket 2a, the user may still use it normally The second interface connector socket 2a; if the manual interface selection switch 4a is selected to the first interface connector socket 1a, the signals of the first interface connector socket 1a and the second interface connector socket 2a will interfere with each other, and the user will not be able to Normal use of the two interfaces may even damage the mass storage device
[0027] As can be seen from the above, the interface conversion of the above-mentioned known mass storage devices obviously has inconvenience and shortcomings in actual use, and needs to be improved.

This invention relates to a method and structure for autoamtically switching large quantity of storage device interface control right including a first interface connector socket, second interface connector socket and an interface conversion chip, in which the said interface conversion chip is used to judge control signal inputted to the second interface connector socket and to decide if the interface control rigid belongs to the first interface connector socket or the second so as to reach the aim of automatically switching interface control right.
Description
technical field [0001] The present invention relates to a method and a device for automatically switching the interface control right of a mass storage device, in particular to a method and a device for automatically switching the interface control right by using an input control signal and according to the level of the control signal. Background technique [0002] Generally, mass storage devices commonly used in computer systems, such as: hard disk, CD-ROM, CD-R, CD-RW, DVD-ROM, DVD-RAM, DVD-R, DVD-RW or DVD+RW, etc. The data transmission with the computer host is through an interface, which can be different transmission interfaces such as USB, IDE, IEEE 1394, serial ATA or SCSI; however, not every mass storage device has a built-in transmission interface that is compatible with the computer host. Compatible, so the current practice is to build several different transmission interfaces in the mass storage device to solve the above problems and provide users with different o...
