Is it possible to figure out a encryption / decryption key if you have only 6 datapoints (inputs / outputs)?
Device ID (input) / (key)

It may be possible in some cases, but not in the general case. I think one can categorically state that if it is, then either the cipher or the key in question is too weak and shouldn't have been used in the first place - unless this is a test or puzzle meant to be solved, rather than an actual practical cryptanalysis problem, of course.
