Streamzap USB remote without using lirc/how to program keys [SOLVED]

graysky · 2013-10-08 19:01:57

I have a Streamzap usb remote which the kernel seems to identify as a keyboard. I'd like to remap the buttons on it and use it without lirc. My google-fu failed me; this must be possible. Any pointers are appreciated.

Upon plugging in the USB receiver, dmesg reports:

[  833.415331] usb 7-2: new low-speed USB device number 2 using xhci_hcd

I found /usr/lib/udev/rc_keymaps/streamzap which seems to map the IR codes to the keys on the remote... what I can't figure out is how to then map a key on the remote to a key on the keyboard.

OK! Figured this out. Firstly, extra/v4l-utils provided /usr/lib/udev/rc_keymaps/streamzap which contains errors. I will file a bugreport. The first line needs to read:

# table streamzap, type: RC-5-SZ

Secondly, it is best to copy that file to /etc/rc_keymaps/streamzap.local and edit that but that requires a modification to /etc/rc_maps.cfg telling it to use the modified file:

*	rc-streamzap             /etc/rc_keymaps/streamzap.local

One can reload the file after making a change to it with this command:

sudo ir-keytable -s rc2 -a /etc/rc_maps.cfg

...where -s rc2 defines the input controller. The default is rc0 but if you unplug the USB it increments up one integer per time.

Here is an example changing the mappings to something mplayer friendly (still a work in progress but you get the idea):

# table streamzap, type: RC-5-SZ

So there you go: streamzap remote without lirc!
