With the progress and development of modern society science and technology and the increasing popularization of digital products, the capacity demand of people on electronic products is increasing. When purchasing electronic products, the size of the storage space of the electronic products is one of the important indicators to be considered, and the capacity of the storage space is also in proportion to the price of the electronic products, and the electronic products with relatively small storage capacity are often finally purchased for cost performance reasons. With the long accumulation of various data, the storage space which is not large originally is more overwhelmed. At present, the most popular method for solving the problem of small storage space of electronic products is to rent a cloud disk, which not only increases the maintenance cost of the products, but also is inconvenient to upload when special data such as confidentiality, privacy and the like are involved. Another method for solving the problem of small storage space of electronic products is to purchase an external mobile hard disk and store the special data separately. However, with the upgrade of electronic products, people will stock various interfaces of storage devices, wherein the storage cards include MMC cards, SD cards, memory sticks, PCIe flash memory cards, XQD cards, CF cards, XD image cards, SM cards, M2 cards, and the like, and the hard disks include IDE, SATA, mSATA, m.2, SATA Express, PCI-E, U.2, and the like. The first major technical problem of fully utilizing these idle storage devices is the complexity of the interface, and the current electronic products.
When a multifunctional card reader sold on the market is connected with a main device, only one data transmission protocol is supported, a new data transmission interface is generally incompatible, and even if the multifunctional card reader is compatible, the multifunctional card reader is only downward compatible. For example, a multifunctional card reader supporting a USB2.0 interface can only transmit data according to the protocol of the USB2.0 interface even if an electronic device supporting a USB3.0 interface is connected. And the USB3.2 interface and the subsequent USB4 interface can only support the USB Type-C interface, so that the USB Type-C interface is not suitable and compatible.

Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.
Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.
The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).
The following is a description of terms referred to in the present application.
AT attachment is the interface standard of IDE (Integrated Drive electronics) hard disk. The method comprises two transmission modes of PIO (Programming I/O) and DMA (direct Memory access). ATA itself can support serial or parallel.
PATA is parallel ATA. Parallel protocols, based on ATA, i.e. IDE interfaces.
SATA is Serial ATA. Serial protocol, ATA based.
SCSI Small Computer System Interface. The storage unit interface mode is specially designed for small computer systems and is mainly used for medium and high-end servers and high-end workstations.
SCSI and ATA are popular protocol specifications for communication between two hosts and peripheral devices, and each has its own physical interface definition. For the ATA protocol, there are IDE interface (parallel) and SATA interface (serial), and for the SCSI protocol, there is SCSI interface.
The SCSI interface is incompatible with ATA/IDE, and the number of interfaces supported is larger than that of ATA hard disks.
Is the SCSI interface parallel or serial? Both are as ATA. Parallel SCSI is based on bus technology, and is slow, only 320MB/sec (Ultra320 SCSI), which has not been able to meet the needs of modern enterprises. Serial SCSI is Serial Attached SCSI (SAS).
SAS is Serial Attached SCSI. The serial protocol, based on SCSI, can be downward compatible with SATA. SAS drive is used for enterprise hard disk, SATA drive is used for consumption hard disk.
The SAS protocol may be divided into three blocks, which are:
SSP is a serial SCSI protocol for transporting SCSI protocols.
SMP is a SCSI management protocol used for maintenance and management of connected devices.
STP is the SATA tunnel protocol used for the transfer of data between SAS and SATA. Namely, the SATA Frame is transmitted as data of the SAS protocol.
In the prior art, the uplink port of the multifunctional card reader is single, that is, the connection end with the read-write device generally supports only one communication protocol, for example, the multifunctional card reader supporting USB3.0 can only be compatible with a lower version communication protocol when being connected with the read-write device supporting USB4, and performs data communication according to USB 3.0. In practical application, the multifunctional card reader needs to perform data interaction with different read-write devices supporting various versions of communication protocols, for example, the read-write device supporting a lightning interface needs to be connected, and the read-write device supporting a USB2.0 interface needs to be connected at the same time, so how to improve the upward compatibility (the compatibility with the communication protocol and the interface at the connection end of the read-write device) of the multifunctional card reader is a technical problem to be solved in the present application.
In this embodiment, the interface adapter includes a first connection interface, a second connection interface, a read/write protocol adaptation module, a media storage protocol adaptation module, a protocol conversion module, and an interface protocol detection module.
