Mate error:  usb drive 'Unable to mount location' Can't mount file

This drive has previously mounted successfully in mate but now it does
not.  In fact I cannot mount ANY usb flash drives from mate.  New,
previously unused, usb keys do nothing more than display the usb drive
icon when inserted. New drives do not even give the error message when
trying to mount hem manually from inside nautilus.

I can mount these devised from the console using:

mount -t msdosfs /dev/da0s1 /media/usbkey

and the data thereon is then made accessible within mate as /usbdrive.

All these problems started after I once attempted to copy the contents
of one usb flash drive to another on this system. Mate did not like
that as I reported at the time but it seems that something basic got
borked and nothing dealing with usb keys in Mate has worked right
since.

Is there some sort of 'reset' switch for mate? I mean, short of doing
the MicroSoft thing and removing and re-instaling the entire software
package?
