Keeping track of the cables, connectors and ports for serial, parallel, mouse, keyboard and Ethernet connections was difficult for even the most advanced users. Another problem with early personal computers had to do with the software that runs peripheral devices. When using a device for the first time, users were required to load software that operated the device, known as a driver.

Most devices came with a disk containing driver software that had to be installed before the device could be used. For many users, the installation process for new drivers was error prone and frustrating. Known as Version 1. USB design supported two transmission modes: low speed ( megabytes per second or Mbps) and full speed (Mbps). The full speed offered a significant enhancement over the speed of serial ports that had previously been used for tasks such as transferring digital photographs or digital music.

A USB -C cable has a connector that is slightly larger than the Mini-B, and both ends of the cable have the same connector. For convenience, the connector is reversible and can be inserted with either side facing up. Dataöverföringen går i båda riktningarna samtidigt, vilket ger en ordentlig hastighetsökning.
