Hello, I have just purchased a B450-f and the USB3 is painfully slow and the USB C connection just won't work. I can't seem to find any driver issues or drivers for the windows 10 that might be the issue. Basically, when transfering data it might start at 10MB/s but soon starts to drop to 605KBs or lower. It then hangs there and if I am lucky speed up to, 2MBs. I have tried every USB3 port and even the USB2 but all do the same speed. Am I missing something or is there a fault?  Thanks |

if you said you've done it in all ports and they actually have different controllers there is a chance that the device you are plugging has a problem -------------

I thought the same but have now tried 3 different devices and even an expansion card but all the same. I can only now presume windows or another application is causing the issue. Sigh |
