Explanation:
Detailed explanation-1: -2 USB 3.0 ports; 2 USB 2.0 ports.
Detailed explanation-2: -The Raspberry Pi 4 contains two USB 3.0 ports and two USB 2.0 ports which are connected to a VL805 USB controller. The USB 2.0 lines on all four ports are connected to a single USB 2.0 hub within the VL805: this limits the total available bandwidth for USB 1.1 and USB 2.0 devices to that of a single USB 2.0 port.
Detailed explanation-3: -Raspberry Pi boards like the Model A+, Model B+, 2, 3, and 3B+ have USB 2.0 ports. The Model A+ only has one, while all the others have four USB 2.0 ports.
