x10 remote cubox

So far i used openelec and an x10 remote control (USB) with my cubox 4. Since I use libreelec (v7.90.010) my remote control no longer works. Comparing lirc config between openelec and libreelec shows no differences. "irw" displays no signals.

lsub:
Bus 001 Device 002: ID 0bc7:0006 X10 Wireless Technology, Inc. Wireless Transceiver (ACPI-compliant)

any ideas, some hint, maybe some modules missing?

thanks
