Abstract

The present invention discloses a data transmission method, which is applied to a first device. The method includes: detecting the device type of a second device connected to the first device; When a device that can share data with the first device, obtain a first signal used to characterize the state of a Universal Serial Bus (USB); wherein, the first signal is used to indicate a data transmission direction; according to the first signal determining whether the first device is a data sender or a data receiver, and notifying a central processing unit (CPU) of the first device of the determination result, so that the CPU performs data transmission according to the determination result. At the same time, the invention also discloses a data transmission device and a USB adapter. By adopting the technical solution of the present invention, fast data transmission between electronic devices can be realized, and user experience can be improved.

Description

technical field [0001] The present invention relates to the technical field of computer processing, in particular to a data transmission method, a device and a USB adapter. Background technique [0002] Currently, there are several ways to transfer and backup files from one electronic device to another electronic device: [0003] Transfer via cloud disk, however, this transfer method is slower; [0004] Transfer via U-disk, due to the small storage capacity of U-disk, it may need to be copied many times to transfer files from one electronic device to another electronic device; [0005] To transfer through a mobile hard disk, although one copy is sufficient in most cases, the purchase of a mobile hard disk requires additional costs. [0006] Therefore, how to conveniently and quickly transfer files from one electronic device to another electronic device has become an urgent technical problem to be solved. SUMMARY OF THE INVENTION [0007] In view of this, the present inv...
