USB 3.2 specification adds a Gen XxY notion for USB3 devices where
X is the signaling rate on the wire. Gen 1xY is 5Gbps Superspeed
and Gen 2xY is 10Gbps SuperSpeedPlus. Y is the lane count.

For normal, non inter-chip (SSIC) devies the rx and tx lane count is
symmetric, and the maximum lane count for USB 3.2 devices is 2 (dual-lane).

SSIC devices may have asymmetric lane counts, with up to four
lanes per direction. The USB 3.2 specification doesn't point out
how to use the Gen XxY notion for these devices, so we limit the Gen Xx2
notion to symmertic Dual lane devies.
For other devices just show Gen1 or Gen2

Gen 1 5Gbps
Gen 2 10Gbps
Gen 1x2 10Gbps Dual-lane  (USB 3.2)
Gen 2x2 20Gbps Dual-lane  (USB 3.2)
