[mythtv-users] Linux: Replacement for lirc_zilog driver

[Justin Alcorn]

I downloaded a 4.15 kernel and installed and booted on it.  plugged back in
my HDPVR blaster.   Looks better, but not quite working:

jalcorn at gossamer:~$ lsmod | grep zilog
lirc_zilog             24576  0
lirc_dev               16384  2 lirc_zilog
jalcorn at gossamer:~$ irsend send_once blaster 0_41_KEY_POWER

hardware does not support sending
Error running command: Input/output error
jalcorn at gossamer:~$ uname -a
Linux gossamer 4.15.0-041500-generic #201802011154 SMP Thu Feb 1 11:55:45
UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

this does. however, seem like a better option at the moment rather than
trying to get the Iguana IR blaster working...because I'm leaving for
vacation tomorrow and I'd like my DVR to be working!
===========
I copied my exact /etc/lirc config from my 16.04 setup, rebooted on the
4.15 kernel.
