Ok, so you're admin.  I assume that `id' lists the administrators
group in your supplementary group list?

Ok, so no UAC.

Not really.  So, with the above permissions, rsync fails but mv works,
right?  What's important when using mv is to mv the file within the
same filesystem.  Rsync does not fail to copy the file to the USB
stick.  It fails when trying to rename the copied file on the USB stick
from its temporary name (.file.foo) to the desired target name.  This
renaming is what we have to check for.  So, what das mv say when you
try to just rename the file?  What if you cp the file to the USB stick
and then try to mv it to another name there?

Can you please create an strace rsyncing just this single file with
the failing permissions?
