Hi Thorsten,

I think you can. The driver should (repeat: should) be capable of 
instantiating twice. In the the config file you can indicate for each 
driver what module (.so file) to load. That way, you can load the same 
module twice. This is done with the File= parameter of a driver. By 
default it loads the same filename as the drivername. For example:

Drivers=hd44780,hd44780keypad

[hd44780]
# this one loads hd44780.so because filename is unspecified
# ... here specify your ususal parameters
type=lcd2usb #or whatever

[hd44780keypad]
File=hd44780.so    # forced filename
Port=0x278
key_direct_0="Menu"
key_matrix_1_4="A"

The first driver loaded is the primary driver and this one determines 
things like display size reported to clients. Keys can come from any 
driver. You can also load the curses driver only to generate keypresses 
for your hd44780 display.

I hope all this information is still true, I haven't played with this 
stuff very much lately.

Regards,
Joris
