You’ve just bought or found an older VIA VT6212L-based 5-port USB 2.0 PCI card . You install it in a desktop PC — maybe running Windows XP, Vista, 7, 8, 10, or even an older Linux distribution. You plug in a USB drive… and nothing happens. Or you get a message: “This device can perform faster” — meaning it’s stuck in USB 1.1 mode. Or worse: the card isn’t recognized at all.
