So (and this was my instant reaction on first reading the thread), is that you might be getting messages that you should expect but naively didn't. You expect a message to say "detected USB drive". You expect a message to say "accessing file system(s)". Except you then ran fdisk and deleted the MBR/GPT! So you're going to get a bunch of (possibly unexpected) messages about filesystems going away and reappearing ... I'm not sure what else is going to happen, but there might be more "unexpected but obvious in hindsight" messages flying around. The other thing. USB. Does all sorts of weird things. Just because your USB stick is USB3 doesn't mean you're going to get USB3 performance from it. Much as I don't like gaming mobos, you can reasonably assume manufacturers aren't gaming the system here - there's too many knowledgable people who will catch them out ... But a possible scenario is the mobo has a single USB3 hub (probable, it can handle 128 devices) wired into the mobo, with a USB2 hub wired into the USB3 hub. I doubt it has a USB1 hub ... But some cheap USB hubs run at the speed of the slowest device - if your scanner is plugged in, live, and advertises itself as USB2, it could downgrade a cheap USB3 hub to USB2! Ouch! Or if it's just plugged into a USB2 port and holding the USB2 hub live! Completely different, but I think I've just debugged a pain point at home. I've got a telco-supplied mesh network, which is crap. So I run ethernet-over-power, which WAS crap. Dunno why. Buy a tp-link router, configure it as an access point over CAT-5, plug the master ethernet-over-power into the access point not the telco hub, and bingo, everything is working so much better! Your trouble with these sticks is probably the same, make a couple of changes that as far as you can see should make no difference whatsoever, but they make a massive improvement instead ...
