A quickly following release of 4.10-rc2 made sure that lirc_dev was loaded together with serial_ir. However, things still don't work. I just need to send some codes. I'm using lirc-0.9.0, which worked fine up to kernel-4.9.1 . With kernel-4.10-rc1/2 there are two bugs. 1) With the same setup - only the kernel has changed from 4.9 to 4.10 - irsend does not work anymore. I get these logs: Jan 7 01:55:23 localhost kernel: serial_ir: unknown parameter 'debug' ignored Jan 7 01:55:24 localhost kernel: serial_ir serial_ir.0: auto-detected active high receiver Jan 7 01:55:24 localhost kernel: rc_core: IR keymap rc-rc6-mce not found Jan 7 01:55:24 localhost kernel: Registered IR keymap rc-empty Jan 7 01:55:24 localhost kernel: input: Serial IR type home-brew as /devices/platform/serial_ir.0/rc/rc0/input10 Jan 7 01:55:24 localhost kernel: rc rc0: Serial IR type home-brew as /devices/platform/serial_ir.0/rc/rc0 Jan 7 01:55:24 localhost kernel: input: MCE IR Keyboard/Mouse (serial_ir) as /devices/virtual/input/input11 Jan 7 01:55:24 localhost kernel: lirc_dev: IR Remote Control driver registered, major 249 Jan 7 01:55:24 localhost kernel: rc rc0: lirc_dev: driver ir-lirc-codec (serial_ir) registered at minor = 0 Jan 7 01:55:24 localhost kernel: IR LIRC bridge handler initialized Jan 7 01:55:56 localhost lircd-0.9.0[2171]: lircd(default) ready, using /dev/lircd1 Jan 7 01:56:52 localhost lircd-0.9.0[2171]: accepted new client on /dev/lircd1 Jan 7 01:56:52 localhost lircd-0.9.0[2171]: write failed Jan 7 01:56:52 localhost lircd-0.9.0[2171]: Invalid argument Jan 7 01:56:52 localhost lircd-0.9.0[2171]: error processing command: SEND_ONCE bat KEY_1 Jan 7 01:56:52 localhost lircd-0.9.0[2171]: transmission failed Jan 7 01:56:53 localhost lircd-0.9.0[2171]: removed client Where under kernel 4.9 things go well like: Jan 7 02:25:08 localhost kernel: lirc_dev: IR Remote Control driver registered, major 250 Jan 7 02:25:08 localhost kernel: lirc_serial: module is from the staging directory, the quality is unknown, you have been warned.

Now kernel-4.10 ruined things, I should at least have the option of using the lirc-made modules instead of serial_ir and lirc_dev. However, the modules that lirc makes when using kernel-4.10 do not offer the possibily of transmission. (It has no variable txsense anywhere in it.) Although compiling says '--with-transmitter', there is something in the kernel source that prevents lirc from building that in. That is not derived from the .config file it finds in the source. I don't know what else it is looking for and doesn't find anymore. Regards, Wim.
