I have since discovered a command "/sbin/mount.fuse" and "fusermount
- -u" which are supposed to allow a non-privileged user to mount and
unmount exfat devices; but I haven't figured out how to use them yet.
A simple "/sbin/mount.fuse /media/xca" or "fusermount -u /media/xca"
do not work. Other than fixing the format of the UUID device indicate
from UUID- to UUID= I have yet to experiment with Don Armstrong's
other suggestions. I thing I would rather get /sbin/mount.fuse and
fusermount -u to work instead.
