Abstract

The invention relates to a universal serial bus device and a method for processing data with the universal serial bus device. The universal serial bus device receives a data package sent out from a host machine, and comprises a first virtual device, a second virtual device and a data distribution device. The data distribution device executes judgment operation which includes the steps that when it is judged that a first virtual address recorded in the data package is the same as the address of the first virtual device, data which are transmitted recorded in the data package and correspond to the first virtual address are transmitted to the first virtual device, and transmission is carried out between the first virtual device and the host machine; when it is judged that a second virtual address recorded in the data package is the same as the address of the second virtual device, data which are recorded in the data package and correspond to the second virtual address are transmitted to the second virtual device, and transmission is carried out between the second virtual device and the host machine.

Description

technical field [0001] The invention relates to a universal serial bus (USB) device, in particular to a universal serial bus (USB) device which does not need to interrupt the currently executing function when adding or reducing functions. Background technique [0002] A Universal Serial Bus (USB) device or a USB device controller (UDC) is commonly used in smart phones to connect to a host, such as a personal computer, to exchange data with the host. When the smartphone is connected to the host, it is regarded as a USB device with one or more functions. After the smartphone is connected to the host, the user cannot increase or decrease functions. For example, when a smart phone is connected to the host, the smart phone is regarded as a USB device capable of data transmission. During the connection, the smartphone cannot add additional camera functions. If you want to add a camera function, you must disconnect the smartphone from the host, and let the host re-prepare the de...
