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.

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]]> Mon, 17 Feb 2020 09:04:19 +0000 https://forum.asrock.com/forum_posts.asp?TID=13667&PID=72879&title=slow-then-slower-usb-3#72879 https://forum.asrock.com/forum_posts.asp?TID=13667&PID=72874&title=slow-then-slower-usb-3#72874 Author: indiecheese

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]]> Mon, 17 Feb 2020 03:05:01 +0000 https://forum.asrock.com/forum_posts.asp?TID=13667&PID=72874&title=slow-then-slower-usb-3#72874
