I was burned once by this sort of Foolishness. (Some USB Drives even have "Blinky Lights", to tell when Activity occurs). I do the File Copy, it comes back to a prompt right away. But then, when I say "sync", it shows how slow Access is, to writing to some of these USB Drives.
Never pull out a USB, until you are *SURE* it is safe to do so. That was a good lesson for me!

After doing the cp or dd to write the .iso to the USB, do you do a “sync” before you eject it? Writing to a USB stick can seem to go quite fast, but that’s because of buffering. Often it takes quite a while (a minute or more for a very big write on a machine with plenty of RAM) to clear the buffers and write thru to permanent media.
Just a thought,
PS: Here’s what I use to write a .iso file to a USB stick:
mate.iso of=/dev/sdc bs=1M conv=fsync status=progress
Hope it helps!
