I suggest you should make these three separate emails, as you have
three separate problems. I suspect this email thread is going to get
messy.

"[F]eel like being destroyed" isn't very specific. What diagnostics did
you run on them, and what were the results?
Can you provide brand name and model? Someone might have experience
with that device. Better yet, the USB identifier that tells us the
manufacturer's name and model. It's two numbers, often separated by a
colon (:), and often four digit hexadecimal values. You can get them
from the command line program lsusb. E.g.:
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Quite likely, what you did wrong was to buy flaky USB sticks. They do
fail unexpectedly, although they are getting better at reliability.
Still, 25% in one month does sound fishy. Are you taking proper
anti-static precautions?

Again, specifics, please. Manufacturer and model number. If USB, the
device identifier as above. What light is flashing, and what does the
printer manual have to say about that light? What error messages do
you get, if any? Log entries?
I wonder if you haven't been hit by a nasty power surge that damaged
your printer and USB sticks. You might review your anti-static
procedures, and test your power cleaning equipment.

What have you tried? Have you tried searching either the Internet or
the Debian packages on suitable keywords. I'd try keywords like "mp4
repair".
