they will both work, but 2.0 will do. Mine is one once used for a printer, it is a normal certified usb-hispeed 2.0 A-B cable.
Use one of the usb2.0 ports (the block furthest away from the eth connector), though it should work on usb3.0 as well.
There are other members using it on a PI 4: Cambridge DacMagic 200M not playing DSD.
So apart from the DSD issue, which nobody can solve for the PI except CamBridge (but they refuse to with “not needed”), it is supposed to work well.
