Getting the /dev/ftape module will possibly need a custom udev rule being written to that it's created when the module is loaded.

Can't help with this I'm afraid. I don't know how to debug kernel modules, nor do I have any ftape hardware. Obviously you won't be able to get anywhere with the udev rules until the modules load successfully :-( Paul. -- Paul Howarth <paul@xxxxxxxxxxxx>
