Sharing HW/data with Android

As Coreelec is used sometimes in a dual boot configuration it would be nice
to list USB extensions that are usable in both OS.
For example an USB keyboard/mouse is better than BT ones that need to be paired.
WIFI and DVBT dongles need to be chosen carefully too.
Some files too could be shared I think of the host file.
and recordings of course.
Please use this post to share your ideas on this subject and any tips.
