The Sonnet Allegro USB-C and Allegro Pro 4-port Type A USB 3.2 cards support the fastest speed of each device independently on each port. The Sonnet cards supports "Multiple Ins", which means that that the host can issue a read request to one endpoint device and then proceed with other transactions without waiting for the response from the first device. Supporting Multiple Ins also improves performance to mutiple Gen 1 devices on a downstream Gen 2 hub connected to a Sonnet card Gen 2 port.
