But USB standard 3 type devices cannot be used in USB 2 type port. But one should keep in mind that USB 2 type devices can be used in USB 3 or USB 2 port. He may use the hub to extend the amount of USB. What will happen if he has more devices to connect? The answer is he has to use a hub. So, usb 2.0 or 3.0 for mouse? Suppose he has connected a mouse and a keyboard through two usb 2 or 3 for mouse and keyboard.
Topology Visibility: A laptop computer may have two USB 2 ports and two USB 3 ports.
In 2017, a 2 TB flash drive was announced by International Consumer Electronics. By January 2013, it reaches a capacity of 512 GB and 1 TB.
Capacity: In 2000, the first USB flash drive was introduced having a capacity of 8 MB. So, if you use an external hard drive enclosure, then it won’t be a problem. Cable Length: So, usb cable 2.0 vs 3.0 and their length? USB version 2 type cable can be of maximum 5 meters long whereas USB 3 type cable can be of maximum 3 meters long. That means it can send and receive data from USB devices simultaneously. Its data communication is a bi-directional or full-duplex. 
That means it cannot send and receive data simultaneously. Its data communication is unidirectional or half-duplex.
Communication Architect: USB 2 has 4 wires inside the cable. So, it can be clearly said that USB 3 port is much efficient in terms of power consumption. So, USB 3 devices can provide more power when needed and also can conserve power when it remains idle. Power Consumption: Power provided by USB 2 is up to 500mA but USB connection provides 900mA. Speed Improvement: Transfer speed rate of USB 2 is 480 Mbps whereas transfer rate of USB 3 is 4.8 Gbps which is 10 times faster than the bandwidth of USB 2 port. So, usb 2.0 vs 3.0? Internally, USB 2 has 4 wires where USB 3 has 9 wires. USB 3 is generally colored Blue on inside to distinguish it from USB 2. Physical Difference: Both USB 2 and USB 3 are physically different.
