When is AMD going to provide proper device drivers for their products? I already RMAed the motherboard twice.
AMD did not update the USB drivers for over than a year now. None of the two boards works properly under Linux. Only the ROG STRIX X370-I GAMING works under Windows 10 with the AMD 3.1 device drivers designed for Windows 7.
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.
Windows 10 with AMD USB 3.1 drivers -> Issues. Windows 10 with AMD USB 3.1 drivers -> There are no issues! Windows 10 with Microsoft USB 3.1 drivers -> Issues. And this is what I found after comparing this one to the ASUS ROG STRIX X470-I GAMING: Then I tried a different motherboard, this time an ASUS ROG STRIX X370-I GAMING. We expect this ASUS motherboard and the ASRock X470 Gaming-ITX/ac must have a similarity somewhere as both failed in similar ways when using USB 3.1, our best educated guess at this stage is that it is potentially a compatibility issue with USB 3.1 redriver chip. It’s difficult to say which USB 3.1 component causes the problem, as it is unlikely to be the controller. Given the MSI B450 Tomahawk successfully completed USB 3.1 testing using the B450 chipset controller we can only assume this is a motherboard specific problem. The only way we were able to complete an ATTO run from start to finish without interruption while using USB 3.1 was with the ASM1351 USB 3.1 to SATA III device and a Transcend SSD370S 512GB SSD. We experienced this bug using a USB 3.1 ASM1352R RAID box and ASM1351 USB 3.1 to SATA III device with the OCZ Trio 150 480GB SSD. USB 3.0 performance was as expected while USB 3.1 performance experienced numerous performance and compatibility issues similar to those we observed with the ASRock X470 Gaming-ITX/ac motherboard.Įffectively, there’s a bug where connected USB 3.1 devices disconnect during heavy and sustained loading.

The second time, after waiting another 3 months, I received a brand new motherboard. Only to find that the same issues remained. The first time I received the same motherboard after 2.5 months. I get normal speeds while using the blue USB 3.0 ports at the back. The same SLOW speeds are observed while using the USB 3.0 ports at the front. I am using an Anker USB-A to USB-C 3.1 Gen2 certified cable. 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. Again the other of the two USB 3.1 red ports works fine under Linux. I have tried the same USB 3.1 port under Linux but the drive never appears. The operating system is Windows 10 64 bit. 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. One of the USB 3.1 red ports works perfectly fine. 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. The motherboards is an ASUS ROG STRIX X470-I GAMING. I am using a USB312SAT3CB SATA III to USB 3.1 Gen2 (10 Mbps) adapter
