I recently was "forced" by Msoft, to perform a cold install of W10. Mostly because they couldn't figure out what was going on and that is the only option they had left. I am seeing performance issues, latency, etc. HOWEVER... after the re-install of W10, I noticed that file transfers from my camera's XQD card were running at about 32MB/s. Prior to the re-install, I was seeing about 290MB/s. I can install the same reader, same cable, same XQD card on other systems and it performs at the 290MB/s rate. I ran USBView and could see that ALL the USB ports were 2.0. My system (Z440) is supposed to have 4 USB 3.0 ports on the front and 4 on the back. All of the ports are now 2.0. Looking for ideas, incantations, magic dust, anything that will help. FYI, I am a photographer and frequently I shoot over 1000 images in a shoot. Unloading the memory card now takes 10x what it used to. Not happy. I am still working with Msoft, but I have no confidence in them whatsoever.
