ROG STRIX X470-I USB 3.1 Gen2 issues

I am using a StarTech.com USB312SAT3CB SATA III to USB 3.1 Gen2 (10 Mbps) adapter

with a Samsung SSD 850 PRO

The motherboards is an ASUS ROG STRIX X470-I GAMING. I am having issues getting one of the USB 3.1 red ports at the back to work with this SATA to USB 3.1 Gen2 adapter. One of the USB 3.1 red ports works perfectly fine. However the other USB 3.1 red port detects the device at USB 3.1, but the drive disappears a few seconds afterwards, and can never be used with this port. The operating system is Windows 10 64 bit. I have tried the same USB 3.1 port under Linux but the drive never appears. Again the other of the two USB 3.1 red ports works fine under Linux.

I am posting here trying to know if somebody else with this motherboard is having issues getting the red USB 3.1 ports to work. I have tried to attach a USB 3.0 Flash drive to the same USB 3.1 red port, but the drive works perfectly fine! The problem arises when a USB 3.1 device is connected to that port.

I am also having VERY VERY SLOW speed transfers between the same USB 3.1 red ports at the back, and a LG G6 smartphone. I am using an Anker USB-A to USB-C 3.1 Gen2 certified cable. The same SLOW speeds are observed while using the USB 3.0 ports at the front. I get normal speeds while using the blue USB 3.0 ports at the back. The cable is this one

Is there anyone with an ASUS ROG STRIX X470-I motherboard who can check if the USB ports are working and report here? Thank you!

This leads me to conclude that there is no proper device driver support for the USB Redriver chip which is needed to transmit the signal to the more distanced port. Only the ROG STRIX X370-I GAMING works under Windows with the AMD 3.1 device drivers designed for Windows 7. None of the two boards works properly under Linux. AMD did not update the USB drivers for over than a year now. I already RMAed the board twice. It is very silly the way manufacturers deal with these issues!

Any way to fix this issue? I can't use my USB-C port from my ROG STRIX X470-I. This is ridiculous.

Do you mean the USB 3.1 port? There are no USB-C ports on the ROG STRIX X470-I.

I'm also having the same problem, my usb 3.1 gen 1 connector (20 pin) is not working. Anyone can share their solution or work around for this issue? I'm using Windows 10, 1903 latest updates.
