OK I have got a work around, but I don't know if it will work with Feodora, this is what I had to do on Debian (I think this more of a bodge than a fix) but I can at least manually mount my USB devices via the cli now. The extract was taken from a debain developer discussion of the problem.

Ok have sussed out a work around
I have got a work around for the time being, for those that
have the same problem here is the bit from the bug report that I have just used
and I can now access my usb hard disk via the cli mount option
-----------------------------------------------------------------------------------------------------
I filed a bug against KDE, but was told that it in fact this problem was
due to Debian's default HAL configuration. Indeed,
editing /etc/dbus-1/system.d/hal.conf to allow
send_interface="org.freedesktop.Hal.Device.Volume" worked.
It's worth noting that any user currently in the plugdev group can use
pmount to mount discs under /media. Perhaps hal should follow this
policy, which seems quite sensible, and shouldn't weaken system
security, since pmount+plugdev is already being used to mount volumes,
etc. The end of hal.conf would then look something like this:
<!-- You can change this to a more suitable user, or make per-group -->
<policy group="powerdev">
<allow
send_interface="org.freedesktop.Hal.Device.SystemPowerManagement"/>
<allow send_interface="org.freedesktop.Hal.Device.LaptopPanel"/>
</policy>
<!-- Allow plugdev members to mount volumes -->
<policy group="plugdev">
<allow send_interface="org.freedesktop.Hal.Device.Volume"/>
<allow send_interface="org.freedesktop.Hal.Device.Volume.Crypto"/>
</policy>

In my case I simply unchecked the bottom two allow send lines and re-saved the
file.
Now when I plug a usb device in it appears on the desktop as an icon, but
right clicking and selecting mount or editing the properties to auto mount
does not work. I have to go to the cli and do:
mount /dev/usbdevice*
*Replace with your usb device name
