I've had a couple of USB storage sticks that did not show up in a machine but were usable in another, or that would sometimes be correctly identified and their partitions exposed, but sometimes were not and only produced disconnection error messages in the logs. After some time, two years at most, they definitely stopped working. But I also experienced some USB devices (a WiFi adapter) that consistently failed to work on a laptop, but always worked year after year on another. Go figure that out. Someone suggested an unhappy match of USB host controller and the gadget's USB bus interface electronics or firmware, who knows?
