See the fuser manpage, particularly the -m option.  Here (Gentoo), fuser 
is a part of the psmisc package, if you don't happen to have the command 
available, but it's likely you do as psmisc is considered quite basic, 
with apps often used by system shell scripts, etc.  (Naturally, run the 
fuser command in a CLI, that is, command-line interface, such as konsole, 
and either use the same to read manpages with the man <manpage> command,  
or use the man: kioslave, typing man: into a dolphin or konqueror window.)

fuser -m should let you know what's using the device, and let you kill it 
if desired (assuming you have appropriate privs, that is, aren't trying 
to kill a root process as your normal user or the like...).  Again, see 
the manpage for the details.
