Ubuntu :: USB Automount Not Working?

today when I inserted my usbpen in the laptop, automount did not work. I tried another pen with same result. I checked with mountmanager and both pens were working and actually mounted them manually, but automount which worked perfectly yesterday now is dead.I found a workaround installing usbmount from standard repository and now automount works again but usbpens are mounted in /MEDIA/usbx instead with their names as before and I have to open a root terminal tu unmount.

Unfortunately I use a pen for backup with unison and changing the mount position I have to modify unison profile every time, which is pretty uncomfortable.The problem May arise from the fact thgat yesterday I tried to manually compile and install the canon driver for my printer and trying to solve dependencies I had to compile and install Glib-2.26 pango-1.28.3 and gtk+2.22 from their sources.I did not manage to get a working canon driver but i may have made a mess with usb automount function.program/service is responsible for usb automount in ubuntu 10.10 so that i can reinstall or reconfigure it.
