Usb 3.0 or 2.0

Hi. Not sure if this has been asked/answered before but do the usb slots on the prime 4 support usb 3.0 or usb 2.0

Some are USB 3 and some are USB 2 - you can tell the difference by the colours, the 3.0 ones are blue.

Thanks for the reply

Basically the two USB in the upper part are 2.0, while the two USB in the front (next to the power connector) are 3.0.
