Don't use mknod. Ever. :)

The device nodes will be auto-created when the drivers are loaded and
able to properly bind to your hardware. Assuming the Pinnacle receiver
is the one driven by lirc_mceusb, then you don't need another lirc
device, /dev/lirc0 handles both receive and transmit.

As for why the serial device isn't working... would have to see dmesg
output after booting. Output following 'modprobe lirc_serial debug=1'
if it doesn't load on boot would also be interesting.
