A Linux Device Driver for USB to USB Direct Link Device

The first version of the Universal Serial Bus (USB) specification was released in January 1996. In April 2000, version 2.0 of the USB specification, which supports transfer rates up to 480 Mbps, was released. Because of its low cost, high data-transfer rate, ease of use, and flexibility, USB has gained wide acceptance in the computer industry. Today, many peripherals and devices connect to computers through USB interfaces. Currently, most general-purpose operating systems pro ....etc

A battery charger, or recharger, is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it.

The charging protocol depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging and can be recharged by connection to a constant voltage source or a constant current source; simple chargers of this type require manual disconnection at the end of the charge cycle, or may have a timer to cut off charging current at a fixed time. Ot ....etc
