From: "taehyun.cho" <redacted> Enable Super speed plus in configfs to support USB3.1 Gen2. This ensures that when a USB gadget is plugged in, it is enumerated as Gen 2 and connected at 10 Gbps if the host and cable are capable of it. Many in-tree gadget functions (fs, midi, acm, ncm, mass_storage, etc.) already have SuperSpeed Plus support. Tested: plugged gadget into Linux host and saw: [284907.385986] usb 8-2: new SuperSpeedPlus Gen 2 USB device number 3 using xhci_hcd Signed-off-by: taehyun.cho <redacted> Tested-by: Lorenzo Colitti <redacted> Signed-off-by: Lorenzo Colitti <redacted> --- drivers/usb/gadget/configfs.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
