Abstract

The invention discloses a universal serial bus line concentration device and universal serial bus line concentration equipment. The universal serial bus line concentration device comprises a concentrator and a singlechip, wherein the concentrator is connected with the single-chip, and the single-chip can control a power supply of a lower connection port of the universal serial bus and a power supply of a main controller of the concentrator, can test current and voltage of fifteen ports of the universal serial bus and can test direct current input voltage of the universal serial bus. By means of the mode, the speed of the interface bandwidth can be increased by adopting a four-to-sixteen interface bandwidth mode, and the test efficiency of testing the universal serial bus can be improved bymeans of the increased speed of the interface bandwidth.

Description

technical field [0001] The invention relates to the technical field of storage, in particular to a universal serial bus hub device and a universal serial bus hub device. Background technique [0002] In the manufacturing process of storage disk memory card, there will be many test procedures using PC (personal computer, computer). One of the test procedures is to write data to the storage disk memory card through the computer PC and then read it out for verification. This test Process Basically every removable storage disk or memory card needs to be tested. [0003] Commonly used hub solutions on the market for testing are generally 2.0 HUBs (hubs) with one to sixteen interfaces. The interface bandwidth is only 40MB (MByte, megabytes). The interface bandwidth on the host is also 40MB+500MB, because the internal junction of the USB (Universal Serial Bus, Universal Serial Bus) 3.0 hub HUB is the bandwidth of Universal Serial Bus USB 2.0 devices, and the bandwidth of Universal...
