For a TerraTec Cinergy XXS USB stick (Bus 001 Device 008: ID 0ccd:00ab TerraTec Electronic GmbH ) I've to switch the protocol every time after plugin to get (at least few) keys working :

$> sudo ir-keytable --protocol=nec --sysdev=ir-keytable 2>&1 | head -n 1 | cut -f5 -d'/'

/me wonders whether "nec" should be set as the default for this key in kernel or not

It makes sense to patch it to use the nec protocol. If not all keys are working, it also makes sense to fix the kernel table to handle all codes, or to point to a new table where all Terratec keys are defined.

Could you please write such patch?

Thank you!

I tried it, but the attached (naive) approach doesn't work. The kernel dmesg shows "kernel: Registered IR keymap rc-dib0700-nec" but keys aren't recognized.

It makes sense to patch it to use the nec protocol. If not all keys are working, it also makes sense to fix the kernel table to handle all codes, or to point to a new table where all Terratec keys are defined.

With this command :

$> ir-keytable --protocol=nec --sysdev=ir-keytable 2>&1 | head -n 1 | cut -f5 -d'/' -w /etc/rc_keymaps/dib0700_nec

I get it to working.

FWIW it is the USB_PID_TERRATEC_CINERGY_T_XXS_2 (ID 0ccd:00ab TerraTec Electronic GmbH) id.
