In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the traditional method, a USB HOST in a blue bridge chip in a test HOST is utilized in a multi-USB parallel detection scheme, a hub with four ports is connected to the HOST, then a hub is respectively connected to each port of the hub to form a test port with sixteen ports, each test port is connected with a USB device to be tested, the 16 devices to be tested are equivalently connected to the same USB HOST, the supportable bandwidth of each USB HOST is limited, and the combination of two layers of hubs can cause the attenuation of signals to influence the signal intensity distributed to each device to be tested.
The invention has proposed a USB mobile storage device quality detection system, please refer to fig. 1, fig. 1 is the structure diagram of the USB mobile storage device quality detection system provided in this embodiment; the system mainly comprises: the test system comprises a test HOST, a plurality of USB HOST expansion cards and USB equipment to be tested, wherein the USB equipment to be tested is connected with the USB HOST expansion cards.
The USB device to be tested refers to a USB mobile storage device to be quality tested, and the specific device type is not limited in this embodiment, and may be a TF card, a USB disk, an SSD, or the like.
The test HOST simultaneously supports a plurality of external USB HOST expansion cards, and the plurality of USB HOST expansion cards are simultaneously externally connected with the test HOST.
Because each expansion card is provided with an independent USB HOST, the test HOST is simultaneously connected with a plurality of USB HOST expansion cards, a plurality of USB HOSTs can be ensured to operate simultaneously, a large number of USB devices to be tested are connected with the test HOST through the plurality of USB HOSTs, the test HOST realizes the communication with the USB devices through the plurality of USB HOSTs (one USB device is only connected with one USB HOST), although a plurality of USB devices to be tested are provided, the number of the USB devices connected to each USB HOST is greatly reduced after the plurality of USB HOSTs are adopted, so that relatively independent communication channels can be realized among the USB devices, different USB read-write data flows can not interfere with each other, compared with the traditional mode of increasing the tested USB devices through HUBs (each USB HOST needs to communicate with a plurality of devices), the problems of scheduling consumption and insufficient bandwidth are effectively reduced, the number of USB HOST expansion cards accessed in a certain range is increased, the USB equipment to be tested is connected to different USB HOST expansion cards as far as possible, and the highest writing speed of each USB equipment can be guaranteed.
For example, the theoretical total bandwidth of USB2.0 is 480Mbps, i.e. 60 mbytes per second, the actual total bandwidth is about 40 mbytes per second, if the maximum writing speed of each USB device is 10M, 4 devices will fill up the bandwidth, and if the maximum writing speed is increased to 16 devices, the writing speed is usually only 2M or lower, in terms of the overhead of bus scheduling. If the scheme is adopted, when each USB HOST expansion card is only connected with four or less USB devices, each USB device can operate at the highest writing speed of 10M, and the detection speed of each USB device is effectively improved.
The mainboard (test HOST) needs to support more external USB HOST expansion cards, the HOSTs on the market generally support 8 at most, and in order to increase the number of USB devices to be tested simultaneously, the customized test HOSTs which can support 16 or 32 external USB HOST expansion cards at most can be selected.

Wherein, x refers to any positive integer, such as 1, 2, 3, etc., and 3.x refers to USB3 series expansion card, specifically to USB 3.1HOST expansion card, USB 3.2HOST expansion card, etc. The expansion card of USB3.x can be used for compatibly testing more USB devices of different versions, effectively expanding the types of the tested USB devices and increasing the universality.
As shown in fig. 1, 2 cables are linked to each USB HOST expansion card, each cable connecting one USB device. Each USB HOST expansion card is connected with two cables instead of the 4 cables supported by the HOST to the maximum extent, so as to ensure that the time consumed for scheduling data between different USB devices on the USB bus is reduced as much as possible during testing, and certainly. Each USB HOST expansion card may also be linked with 3, 4 or any other cables, which is not limited in this embodiment.
