USB 3.0 cables are compatible with USB 2.0 devices, but the performance of these connections is only as fast as it would be at 2.0 level. This new specification introduced more bandwidth for transferring data, an increase in power output to improve charging and powering of devices and more robust power management. USB 2.0: The USB 2.0 specification was released in 2000 and increased the amount of bandwidth from 12 Mbit/s to 480 Mbit/s (Megabits per second).

This defines the cables, connectors, and communication protocols that facilitate communications and power delivery between computers and/or electronic devices.As time has gone on, the USB standard has evolved to become more efficient and adoption among device manufacturers so wide spread as to make different kinds of USB connectors ubiquitous.

The reality is that not all USB cables are created equal and there are differences in USB ports. Once you finally come across a USB cable, you try to plug it in, only to realize that the connector just doesn’t fit. You frantically search through your cupboards, drawers, and bags, untangling the wires as you go. You need to connect to a printer, camera, or cellphone, but you can’t find a USB cable. Does this sound like a familiar situation?
