If I understand correctly, you mounted the USB device via command line
but unmounted it via the GUI?  Unless I am mistaken that is not
permitted in gnome.  I believe the last time I tried that it gave an
error saying it was mounted via command line therefore must be
unmounted the same way.  Perhaps the same applies with KDE but KDE is
failing to give that message  and thinks that it unmounted it.  Check
your mount command after unmounting via KDE to see if it really is
unmounted or if KDE mistakenly believes it to be.  Because that would
certainly cause the error you noted.  The bug would be with KDE not
properly detecting that it was mounted via the command line and
therefore must be unmounted the same way (unless KDE upon detecting
that can unmounted it appropriately.

I'm not clear what you want the script to do.  If it's simply to mount
via the command line, then you simply put what you typed at the
command line into a script (you can technically omit the #!/bin/bash
for that case).
