There are two main USB ports in general use at the current time; USB 2.0 and USB 3.0. Devices that adhere to the USB 2.0 standard have the ability to transmit data at a maximum speed of 480 Mbps. The USB 3.0 standard can transfer data at up to 625 Mbps.
A blue USB port signifies 3.0 USB. A black USN port signifies 2.0 USB.
Although USB is generally backwards compatible, sometimes this is not always the case. For example, some users experience difficulties using USB 2.0 devices with USB 3.0 ports on some computers.
In this case, it is recommended that users try a different USB port on their computer. If this does not provide the required result, we suggest a powered USB hub such as the Icon One Hub;
