I checked and the same versions of both files are found in the source and target folders. Besides that, the system doesn't let me replace both files in the INF folder. I probably should run an elevated File Explorer.
There is no usbstor.sys file in the INF folder, but there is one in the FileRepository\usbstor.inf_amd64..... folder. I think the sys file should be copied
somewhere else. But I don't think this is the problem as long as ALL other USB storage devices work fine.
