In theory, snd-usb-audio should be loaded after the firmware.

Put the script into /etc/hotplug/usb, and create another file named
scriptname.usermap containing the vendor/product IDs of the device.
The files I'm using in the loader for M-Audio's closed source firmware
are available here:

The kernel passes the usbfs file name to the hotplug script in the
environment variable DEVICE. (fxload will use this variable by
default.)

You could try "modprobe snd-seq-dummy ports=10" and connect those
ports by hand to your synths, but then you'd have quite unintuitive
port names.

Currently, ALSA doesn't allow to choose/change the client number of
software synthesizers.

It would be nice if sequencers would support assigning ports by name.
The MMA has defined a meta event for this, but AFAIK nobody uses it.
