MCE receiver problem

Hello,

maybe this is not exactly a lirc problem. Please point me to correct location 
if i am wrong here.

I've got a MCE-like ir remote together with a USB receiver.

Looks like it is detected by the kernel and a input device was created. 
Most of the keys are working. But - for example - the color buttons do not 
generate any output.

ir-keytable (version 1.10.1) returns:
  Couldn't find any node at /sys/class/rc/rc*.

Using for test
  ir-keytable -d /dev/input/eventxx -r
i got:
------------------- cut --------------------
  scancode 0x700e0 = KEY_LEFTCTRL (0x1d) 

  ...
  Enabled protocols: other lirc rc-5 jvc sony nec sanyo mce-kbd rc-6 sharp 
xmp 


There is no definition of the color buttons in the list above.

/sys/class/rc/rc*).

Tests were done using this command:
  ir-keytable -d /dev/input/eventxx -t

Any hints ?


Is it possibe to see the scancodes received by the USB-receiver to validate 
that the remote really sends data for the color buttons.
(and i am not barking at the wrong tree)


Some info about my system:

Kernel 4.9.6 (amd64) custom configured
Distribution: Gentoo

lsmod output:

The remote looks like this one:

but its branded as olidata.

The receiver is detected as (syslog):
