The error you get while trying to mount usbdevfs is a good thing - it
shows ussbdevfs is already mounted. Well there is one other thing, is
generic SCCI support enabled? This can be compiled into the kernel or
loaded as a module. lsmod should show the generic SCCI module as sg.
For example on my system, I get:

jpk@debian:~$ /sbin/lsmod | grep sg
sg                     24420   0 (unused)

And if SCCI support is in the kernel (either as a module or compiled
in) and you still get an error trying to mount /dev/sda1, then I would
suggest trying to mount another SCCI drive. ie. Try
mount -t vfat /dev/sda2 /mnt/usb/
or 
mount -t vfat /dev/sdb1 /mnt/usb/

I am not sure but I seem to recall that with generic scci, the first
'thingy' to use it gets the first scci device ie /dev/sda and the next
'thingy' gets the next scci device. So if something is using /dev/sda1
- for example a cd writer - then the usb device will be the next
available scci device.
