Hello, I have annoying problems with my usb on my MSI B450-A Pro AMD motherboard. It has been a problem for a while now. It may be a motherboard defect. My keyboard and mouse work fine, but usb sd card readers, usb flash drives have intermittent issues. My sd card readers most of the time are not recognized. Once in awhile my flash drives stop working and not recognized by Windows. It appears to not be a problem with the operating system or drivers. It happens on all three of my Windows OS's in a multi boot Windows system. The drives work fine on other Pc's.In device manager I receive an error message when attempting to use the card readers,
"Windows cannot use this hardware device because it has been prepared for "safe removal", but it has not been removed from the computer. (Code 47 )t o fix this problem, unplug this device from your computer and then plug it in again.
I ran SFC and uninstalled the drivers a few times.The board uses M.S. 3.0, 3.1 drivers and I tried to update the drivers in device manager and said the best drivers were already installed.
As a side note, I was using a 3.0 usb hub and the ports onboard. Same outcome. I'm getting frustrated with this, so if anyone has any ideas, I would appreciate any ideas. Thanks.
