USB connection employs a widely-recognized symbol, so it’s impossible to mix it with some other socket in the PC. Oftentimes devices with a USB socket require a cable to be connected with the computing machine; however, some items (mice, keyboards, etc.) feature this cable permanently, or use an integrated connector (flash drives) that must be plugged in directly to the interface.
As a rule, it’s feasible to start working with a USB item once it’s plugged in. That might be due to the OS ability of automatic search for the needful USB devices drivers with their instant installation. Alternately, the user has to upload a special disk to the ODD bay and install manufacturers’ batch of drivers.
Once a user plugs the device, it starts communicating with the system; this enables the full range of operations possible to realize with the connected gadget: viewing, reading, recording, transferring, displaying data of various kinds (text, audio, video). Moreover, serial bus frequently enables charge-in process parallel to other operations. For instance, it’s possible to transfer photos from a camera and simultaneously charge it from PC.
Special attention should be drawn to the disconnecting of devices with a USB interface. If you unplug the equipment still running, there is a chance of losing some information. To prevent such an issue, it’s required to wait till OS completes saving all necessary information; with the aim to optimize storing and data transfer, one has to download drivers for USB devices.
How would one know if the system completes data saving? Practically all USB gadgets have activity lights. Hence, when all data is already stored, this activity light turns off. That is a sign for the user that the item might be safely removed.
