Description

removable storage device

technical field

The utility model relates to the technical field of storage, in particular to a removable storage device with an OTG function.

Background technique

Among the existing removable storage devices, the most common one is a USB flash drive. The full name of U-disk is USB flash drive, and the English name is USB flash drive, which is a miniature high-capacity mobile storage product that uses a USB interface without a physical drive.

The full name of USB is Universal Serial Bus (Universal Serial Bus), which is a data transmission bus jointly proposed by Intel, Compaq, IBM, Microsoft and other companies in 1994 to standardize the data connection and communication between computers and external devices. communication.

The development of USB technology enables PCs and peripheral devices to simply connect various devices for data transmission through the USB bus, and as the peripherals of the PC, data exchange is performed under the control of the PC. However, once this convenient exchange method leaves the PC, the USB ports cannot be used to operate between the devices, because no slave device can act as the same Host as the PC.

OTG is the abbreviation of On-The-Go. It is a technology developed on the basis of USB technology. It makes USB devices get rid of the limitations of the original master-slave architecture and realizes the end-to-end transmission mode.

At present, on small portable devices such as mobile phones, tablet computers, and cameras, due to volume reasons, it is impossible to set a standard-sized USB type A (standard A) interface like a desktop computer or notebook computer, but only a microUSB with a smaller interface area. interface (mini-USB interface). Nowadays, more and more portable devices with microUSB interfaces support traditional U disks to use OTG cables to exchange data with them. It is connected to the microUSB interface on the computer, so that data can be exchanged between the microUSB portable device and the U disk. However, once the OTG cable is removed, data exchange between traditional U disks and mobile phones and other devices is no longer possible. The OTG cable is inconvenient to carry and also brings inconvenience to users.
