Getting the Streamzap USB remote to work under Linux is very easy. The recommended method is to use LIRC as it provides the ability to map the same keypress to different actions under a variety of applications. Alternatively, v4l-utils and any modern Linux kernel works too but is less flexible.

This repo contains instructions and files to allow operation with LIRC or v4l-utils and also gives specific config files for mythtv, kodi, and mplayer. Use only one of the two options presented.

• Install lirc for your distro. Note that by default, lircd runs as root user. However, for increased stability and security, upstream recommends running it as an unprivileged user. See Appendix 14 and/or this Arch Wiki page for that setup.
• Place 00-Streamzap_PC_Remote.conf in /etc/lirc/lircd.conf.d/ (note this was regenerated using lirc 0.9.4b to prevent some key doubling observed with the original file).
• If using Xorg, place 90-streamzap-disable.conf in /etc/X11/xorg.conf.d/ to keep the remote from being seen as a keyboard.
• If not using Xorg (for example on some ARM devices such as a Raspberry Pi), blacklist the offending modules by placing streamzap-blacklist.conf in /etc/modprobe.d/ to suppress this behavior.
• With the release of lirc v0.9.4a (June of 2016), users need to edit upstream's provided /etc/lirc/lirc_options.conf with these changes:

driver          = default
device          = /dev/lirc0

• Start lirc using your init system (systemd, openrc, upstart, etc.)

• Place .lirc/ into your homedir.
• Place .lircrc into your homedir.
• For mythtv only, create this symlink: ln -s ~/.lirc/mythtv ~/.mythtv/lircrc

• Place kodi/Lircmap.xml into ~/.kodi/userdata/
• Optionally place kodi/remote.xml into ~/.kodi/userdata/keymaps/
• Optionally place kodi/audio_switch/audio_switch.py in ~/bin/ (note you likely need to edit the code to match your system, see the thread in the comments of the file).
• Optionally place the two suggested icons into ~ as shown in the script.

• Upstream control file
• mplayer -input keylist
• mplayer -input cmdlist

• keyboard.xml
• remote.xml
• List of built-in function

• Install the v4l-util package (your distro provides this in all likelihood).
• Modify /etc/rc_maps.cfg so the streamzap line points to /etc/rc_keymaps/streamzap.local

• streamzap.local should be installed to /etc/rc_keymaps/

The syntax of the keymap scancode button_name

Execute ir-keytable without any arguments. Example:

# ir-keytable
Found /sys/class/rc/rc0/ (/dev/input/event3) with:
	Driver streamzap, table rc-streamzap
	Supported protocols: NEC RC-5 RC-6 JVC SONY SANYO LIRC RC-5-SZ other
	Enabled protocols: RC-5-SZ
	Name: Streamzap PC Remote Infrared Rec
	bus: 3, vendor/product: 0e9c:0000, version: 0x0100
	Repeat delay = 500 ms, repeat period = 125 ms

Execute ir-keytable --read --device=/dev/input/PATH where PATH is what the previous command outputted (event3 in the example above).

The lirc package is likely required. Execute irrecord -l to see a list of all available button names.
