USB stands for Universal Serial Bus and is used to facilitate connection between the host computer and several peripheral devices. It was created as a replacement for other buses such as parallel and serial buses. USB is more advantageous than these other buses since it supports almost all device types which are attached to the computer. Furthermore, it functions at a higher speed than the other buses. Other advantages include the fact that it only services as a medium of communication from the device to the host and vice versa without having to know the specific structure as well as meaning of the data that it is delivering. USB enables devices to ask for fixed bandwidth as it transfers data so that it can support video as well as audio. USB connects computer peripherals such as mice, PDAs, joysticks, printers, keyboards, gamepads, scanners and flash drives.
Unless you update your drivers regularly you may face hardware performance issues.
To check your drivers you should manually verify every device on your system for driver updates
USB devices connect through hubs. One hub which is always in existence is referred to as the root hub and it is in- built within the host controller. Sharing hubs are also available in host controllers and they permit several computers to contact a single peripheral device. They function by switching access between personal computers automatically and even manually. This is especially useful in small-office environments. USB is able to support low speed signaling rates (1.5 Mbps), full speed (12 Mbps) rate. USB 2.0 also supports hi-speed 480 Mbps and USB 3.0 supports SuperSpeed 5.0 Gbps. A Benq USB driver is one which supports the operation of Benq USB devices. For this device to function properly and efficiently, it is advisable for the user to ensure that he or she is using the latest version of the device driver as an old one will create conflict. It is highly recommended you run a free registry scan for and Benq USB driver errors before installing any driver updates.
