This is really a question that is more appropriately directed towards the
maintainers of "Cygwin Easy", since that's a separate project and anything
we might say here may not be appropriate for "Cygwin Easy".   That said...

Cygwin is not Linux (or Unix or BSD or....)  It has no file-system drivers
and relies on Windows to provide file access.  Translation - you cannot
mount a file system with Cygwin like you show above.  Cygwin's mount is
not too much more than a mapping of Windows-style paths to POSIX ones.

In general, if you can do it with Windows, you should be able to do it
with Cygwin and that may translate into being able to do it with "Cygwin
Easy".  But to do it with Windows means you need an NTFS file system on
your USB disk.  If that's a problem for you, then I believe you have
provided the answer to yourself. ;-)
