Many computers still come with USB 2.0 ports as well as USB 3.0, and many users still work on systems that have no USB3.0 connectivity at all. Then again you may not There is also a question of backwards compatibility. You can't tell by looking except the connector has a blue plastic strip inside instead of white. It fits just as if the port was a USB 2.0 port. USB 3.0 ports, you just plug the USB 2.0 connector in. USB-2.0-Kabel können an USB-3.0-Hosts benutzt werden USB-3.0-Kabel können an USB-2.0-Hosts benutzt werden, erfordern dann aber USB-3.0-Endgeräte. You'll be able to maximize your bandwidth when using a USB 3.0 cable with USB 3.0 devices and ports, otherwise plugging a 3.0 device into a 2.0 port or a 2.0 device into 3.0 a port will get you standard USB 2.0 data rates USB-3.0-Kabel können aufgrund der Anbauten nicht mit USB-2.0-Endgeräten benutzt werden - USB-3.0-Typ-B-Stecker sind nicht abwärtskompatibel.

The Standard-B is used at the device side Your existing USB 2.0 gear will work on version 3.0 ports and vice versa. However, it is not possible to plug a USB 3.0 Standard-B plug into a USB 2.0 Standard-B receptacle, due to a physically larger connector. Backward compatibility applies to connecting a USB 2.0 Standard-B plug into a USB 3.0 Standard-B receptacle.

For example, if you connect a USB 2.0 drive or earlier versions to a USB 3.0 port, the drive will work as normal A USB 3.0 Standard-B receptacle accepts either a USB 3.0 Standard-B plug or a USB 2.0 Standard-B plug. So as for power management and power consumption, USB 3.0 is more advanced than USB 3.0. The USB 3.0 devices contribute more power when required and conserve power when the device is connected but idle. USB 2.0 beschränkt auch schnelle USB-3.0-Sticks auf maximal 40 MByte/s, vor allem ältere USB-2.0-Sticks kommen jedoch nicht einmal in die Nähe dieser Grenze. This has led to a different registry structure from that observed with USB 1.1 and USB 2.0 host controllers leading to compatibility issues.

Unlike its predecessors USB 3.0 is bidirectional which means that it can read and write data at the same time USB 3.0 did not exist prior to Windows 8 and as such Microsoft did not have driver support for USB 3.0 host controllers. It also means that you can plug in USB 2.0 on USB 3.0 port but the performance will be that of USB 2.0. USB 3.0 is backward compatible which means that if you have a USB 2.0 port your USB 3.0 will work as well as a USB 2.0 on that port. You can plug a USB 2.0 device into a USB 3.0 port and it will always work, but it will only run at the speed of the USB 2.0 technology
