USB: show USB3 Gen XxY version during device enumeration
PATCH 2/2 USB: show USB3 Gen XxY version during device enumeration
Hi,
Quoted 20 lines · Mathias Nyman
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. USB 3.2 supports dual lane Gen Xx2
Gen 1x1 5Gbps single lane
Gen 2x1 10Gbps single lane
Gen 1x2 10Gbps dual lane (USB 3.2)
Gen 2x2 20Gbps dual lane (USB 3.2)Signed-off-by Mathias Nyman <[email protected]>--- drivers/usb/core/hub.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-)drivers/usb/core/hub.c +0

SuperSpeedPlus is not a Synonym to Gen2, is it? Perhaps Gen XxY should be printed at a later time when you finally have Speed and Lane count for both RX and TX sides?
