I have an i.mx8qxp-mek board． The U-Boot's version is
U-Boot 2017.03-imx_v2017.03_4.9.88_imx8qxp_beta2+g84c4e82 (Jun 28 2018 - 09:07:20 +0800)
I tried to use u-boot command "ums 1 mmc 1" to simulate the board as a u-disk to a host(windows 7 64 bit).
However, after the u-disk shows on windows, I find it works at USB2.0 high-speed mode instead of super speed mode.
This can be seen by checking usb port from host with some software or by adding print info from u-boot.
I am sure of the host port is a USB3.0 PORT and the USB typeC-typeA cable supports 5gbps.
My questions are:
Does the usb-ss(type-c port) support supper speed when working in peripheral mode?
If yes, are there any example software(u-boot or Linux or others) can show this?
