USB 3.0 on Usb 2.0

[vnyteck]

hello,
i am planning to buy a Kingston 16GB USB 3.0 Pendrive, will the USB 3.0 can be use in 2.0 Ports, is it compatable with USB 2.0 and is it also compatable in USB 1.1 ?

 

[AMD X6850]

Yes, USB3 is backwards compatible with USB 2 and 1.1 but it will run at slower speeds because they cannot support the faster speeds of USB3.

AMD X6850 is correct. If you look at the specifications for USB 3.0, it's just USB 2.0 plus four (?) more wires. Without those four wires, it is identical to USB 2.0
