Embodiment Construction

[0017] A Universal Serial Bus device such as Figure 1 to Figure 5 As shown, it includes an OTG controller 10 for connecting two external devices for data exchange; a first plug 20 for plugging in a first external device; a second plug 30 for plugging in a second external device; OTG The controller 10 communicates with the first plug 20 and the second plug 30 respectively, and communicates with the first external device and the second external device through the first plug 20 and the second plug 30 communicated therewith; it also includes a switching device 40 for Control whether the communication between the first plug 20 and the second plug 30 is processed through the OTG controller 10 . The switching device 40 has two working states. When it is in the first state, the OTG controller in the universal serial bus device is connected and has an OTG function, and can realize data transfer between slave devices without a host (Host). Transmission; when being in the second state,...

Abstract

The invention relates to the field of electronic communication, and discloses a USB (universal serial bus) device, which comprises an OTG (on-the-go) controller, a first plug, a second plug and a switchover device; the OTG controller is used for being externally connected with two piece of externally connected equipment to perform data interchange; the first plug is used for being plugged with the first externally connected equipment; the second plug is used for being plugged with the second externally connected equipment; the OTG controller is respectively communicated with the first and second plugs; the switchover device is used for controlling the communicating state of the first and second plugs and performing data processing by the OTG controller. The USB device can realize the data connection between mobile equipment or connection between a computer and the mobile equipment or be used as a power supply line for charging the mobile equipment or a battery by changing the work state of the switchover device, so the universality and portability of the USB device is improved.

Description

technical field [0001] The present invention relates to the field of electronic communication, more specifically, relates to a universal serial bus device with multiple functions. Background technique [0002] Universal Serial Bus (Universal Service Bus, referred to as USB) was originally a data transmission bus initiated by Intel, Microsoft, Compad, IBM, NEC and other major manufacturers. Its biggest feature is that it supports Hotplug And plug and play (Plug&Play), so its use is far more convenient than PCI bus and ISA bus. According to the standard definition of USB, USB devices are divided into USB host (HOST) and USB slave (SLAVE). Data transmission can only be realized when a USB master device is connected to a USB slave device, wherein the personal computer is a host device, and the device connected to the personal computer is a slave device. [0003] The development of USB technology has enabled PCs and peripheral devices to connect devices with various data transm...
