All my USB sticks worked fine until my Windows 10 Pro Desktop was upgraded to 19042-804. Now when I have a stick inserted and try to boot the boot hangs trying to load the motherboard microcode. As soon as I remove the stick it continues and boots fine. Also, when I insert a stick after it has booted I get a " USB Not Recognized" The last USB device you connected malfunctioned... I've tried several sticks. All worked prior; now all give the same error. System says USB driver is up to date. I've a keyboard, mouse and external hard drive connected via USB and they all work fine.... Just the USB sticks have the problem. Anyone else seeing this with the new release?
