Alright so I did a bit more testing.
the pfsense lcdproc package doesn't include the driver i need, LIS.so
So I uninstalled it, and manually installed the latest freebsd pkg from
ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8.1-release/All/lcdproc-0.5.3.tbz
to my dismay, this also didn't include the lis.so driver (even though it should according to lcdproc's documentation)
I did some more reading and it looks like the LIS driver needs libftdi to function properly, so I installed that from
ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8.1-release/All/libftdi-0.17.tbz
I uninstalled and reinstalled the lcdproc freebsd pkg, and still no joy.
it seems like just about nobody has tried to use this driver on freebsd/pfsense/monowall/freenas
I did find an article on using this in MYTHTV:
http://www.mythtv.org/wiki/Nmedia_pro-lcd
it looks like I might be able to get this running if i install from source (that way I can tell it which drivers to install, and force the LIS driver)
but this is where im completely out of my element.
Can someone please get me moving in that direction? I'd really appreciate it.
My eyes are bleeding at this point. too much reading.
The other thing that comes to mind - this is a driver that should be included in the pfsense package, but isn't. So perhaps there's some technical reason that this simply won't work on freeBSD/Pfsense?
