Vorrei sapere se il mio computer desktop supporta USB 3.0
, ma dall'output di seguito sembra improbabile.
Ottengo il seguente output da lspci
:

Dopo tutte le porte USB rilevate come USB 1.0, non USB 2.0 , sto anche pubblicando output di lsusb -t

Capisco correttamente che solo due slot supportano USB 2.0? E se è così, come posso individuare esattamente quale slot fisico supporta USB 2.0?
USB3
controller a un computer desktop?
