We often use a device that expands a USB to multiple USB ports. It is called a USB HUB. It has a USB port to connect computers and multiple USB ports to connect devices. In turn, if you need a USB port to connect the device, multiple USB ports to connect the computer? This device is called a USB sharer, or USB SHARE. The USB sharer is used to share a USB device on multiple computers via the USB port. For example, if there are often multiple computers sharing a single printer, a USB share device is required.
A true USB smart sharer requires no settings, no hardware switch, no software switching. Since the USB host will read data from the USB device even if the USB device is not used, the USB sharing technology that is not required to be set is a very complicated technology. Traditional USB sharers either switch manually with a switch or use software to switch. Implementing USB-free sharing is a world problem for many years in this area. Recently Boskar finally solved this problem. At present, Bosch Card's USB intelligent share device achieves no manual switching and no control switching software.
The use of the Boscard USB Smart Share Device is very simple. The two host-side USB ports of the sharer are respectively connected to the USB sockets of two computers via a USB cable (printing line); one device-side USB port of the product is used to connect the USB. equipment. There are 2 LED indicators next to the USB port on the device side to indicate which USB host is strobed. When two USB ports on the host computer are connected to the smart USB sharer, the product will intelligently select the host to be accessed later. In actual use, the USB device is connected to the newly inserted host USB port, which is equivalent to a "plug and play" effect. If you want to manually switch to a host, simply unplug the USB print cable and then plug in or restart the host. Since there are two USB power supplies of the host computer and almost no self-consumption power, the drive capability of the USB device is more than that of a computer USB port, which is nearly 2 times. Since the use of a sharer is the same as an ordinary cable, it does not require a driver; only a transparent physical switch is implemented, which is independent of the computer operating system and does not require any operating software.
