There is clearly an error here and on the Trezor website. Both devices are shipped with USB type A connector on one end. Obviously, you wouldn't be able to plug in USB-C into micro-USB port and vice-versa, so I don't think it's necessary to mention.
Yes, that is clear enough for me.
First thing, check the USB connector it might have full of dirt and rust to remove them use a brush and lacquer thinner(Or any rust cleaner, alcohol, or fluid) then test it again.
maybe frequently Trezor user must have PortPlugs to cover USB port form dust.
