Hello all, first post here. I ran into the troubles in this thread, but found a new USB drive that works with the ME1 out of the package. This has been confirmed with two identical drives, one new and one formatted on a Win10 machine. I was able to upgrade the firmware and save configurations with no problem. If you just want to go out and buy a drive that just works, you might try this one.
Samsung MUF-32AB FIT Plus 32gb
