How to change ownership of subdirectories under /media

[Haines Brown <haines@histomat.net>]

I want to enable a user to copy files to a USB key mounted on a directory 
under /media. 

I can change the ownership of that directory to that of the user, but 
when I mount the the key on it the ownsrhip reverts to root. As the 
result a user cannot copy files to the key. I would enable the user to
copy files to the key and preserve their ownership.

This must be a common problem, but I have not found a solution on 
line or in man mount.
