Computer peripherals are constantly being updated, and various computer interfaces are responsible for communication and information exchange between computers and internal and external devices. Veterinary B-ultrasound systems also use these technologies. To this end, various computer manufacturers have designed and launched a wide variety of interfaces and interface specifications, such as PS/2 interface, PCI interface, ISA interface, and serial and parallel interface. However, while these interfaces solve the initial communication between computers and internal and external devices, they also have various defects, such as: using non-shared interfaces, large interface size, different specifications, etc. In order to solve the various defects of the above interfaces, computer manufacturers and users urgently need a new peripheral connection method. Against this background, USB came into being, and the USB on veterinary B-ultrasound was also created in this way.

The USB interface technology in the veterinary B-ultrasound system not only provides a new connection method for computers and peripheral devices, but also frees the computer interface from the shackles of the traditional I/O mode. The USB interface technology in the veterinary B-ultrasound system has advantages that traditional interface technologies do not have:

Veterinary B-ultrasound

(1) Low cost. The USB standard in the veterinary B-ultrasound system can connect peripheral devices and computers at a very low cost. In order to facilitate the manufacture of computer USB peripherals, all USB-related intelligent mechanisms exist in the chipset of the computer host.

(2) Hot plugging. The USB in the veterinary B-ultrasound system realizes true plug-and-play function. After the device is connected, the USB will automatically detect and automatically configure the software. After completion, it can be used immediately without the user performing other operations to configure the I/O address and interrupt request. When there is a plug-in or unplug action on the computer USB interface, the host can scan and identify these USB peripherals and load and unload the corresponding device driver, truly realizing the plug-and-play function.
