LIRC 0.8.3 added several new devices which still seem to be missing in lirc-0.8.3-r1.ebuild (see NEWS file in LIRC package for details).
For example, the new "samsung" driver should be added to IUSE_LIRC_DEVICES_DIRECT.
Steps to Reproduce:
Also, the new "irlink" driver should be added to
IUSE_LIRC_DEVICES_DIRECT and LIBUSB_USED_BY_DEV
I have added "irlink" to IUSE_LIRC_DEVICES_DIRECT and LIBUSB_USED_BY_DEV in lirc-0.8.3-r1.ebuild
add to /etc/conf.d/lircd
LIRCD_OPTS="-H irlink -d /dev/ttyUSB0"
irlink device works!
P.S. about my irlink device:
Bus 003 Device 004: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC
Added options irlink, commandir, ite8709 and samsung to lirc-0.8.4.ebuild
