SM7-SBASE-EN4(AIO-1684XQ).USB ports don't work

yujin_007

Hi. all!
The USB ports on the AIO-1684XQ board (stock firmware) don't work when connect on either USB 2.0 or USB 3.0 devices. Power is supplied to the ports, but there's no packet exchange on the USB bus (checked with a USB sniffer). However, a USB2SATA device is detected correctly.
Also I'am noticed that /proc/device-tree/ doesn't mention gpio with the "*usb*" label.
Who has this board, could you post the correct dts and -setup.sh files that install the necessary gpio-led at boot to work with USB devices?

The problem was solved by removing the module, blowing it out and degreasing the ASM1074(gpio control is not required - POR_N is pulled up via a resistor) components.
