Please help with FTDI 232 and lirc - almost works I think

[VDR U. <use...@gm...>]

Hi. I currently have a homebrew serial IR working with lircd
0.9.3-devel but I now want to get it working with a usb FTDI TTL232R
IR. The config.log shows that ftdi support should be compiled:
#define HAVE_LIBUSB 1
#define HAVE_FTDI 1

After compiling I do have ftdi.so and ftdi.la.

Next, I don't know if I'm supposed to load the ftdi_sio module but
when I do it seems like something good happens:
[ 1809.269780] usbcore: registered new interface driver ftdi_sio
[ 1809.269863] usbserial: USB Serial support registered for FTDI USB
Serial Device
[ 1809.270774] ftdi_sio 7-1:1.0: FTDI USB Serial Device converter detected
[ 1809.270937] usb 7-1: Detected FT232RL
[ 1809.275083] usb 7-1: FTDI USB Serial Device converter now attached to ttyUSB0

Then I try to start lircd with "lircd --logfile=/logs/lircd.log" and
check the logfile:
lircd: Info: Initial device: /dev/ttyUSB0
lircd: Info: Initial device: /dev/ttyUSB0
lircd: Info: Using remote: 20.1_IR.
lircd: Notice: lircd(ftdi) ready, using /var/run/lirc/lircd
lircd: Notice: accepted new client on /var/run/lirc/lircd
lircd: Info: Initializing FTDI: /dev/ttyUSB0
lircd: Error: device configuration option must contain an '=': '/dev/ttyUSB0'
lircd: Warning: Failed to initialize hardware

I have no clue how to fix that error. Apparently the `device
configuration` needs an equal sign somewhere, but where? I couldn't
find an example anywhere that applies to lirc-0.9.2 or higher.

My lirc_options.conf is:
[lircd]
nodaemon        = False
driver          = ftdi
device          = /dev/ttyUSB0
output          = /var/run/lirc/lircd
pidfile         = /var/run/lirc/lircd.pid
plugindir       = /etc/lirc
permission      = 666
allow-simulate  = No
repeat-max      = 600

My goal is getting the FTDI ir receiver to work with lirc, so I can
then use my remote control with VDR. So my questions are:
1. Am I supposed to load ftdi_sio when using FTDI with lirc?
2. Do I have to load lirc_dev?
3. What's the correct settings for lirc_options.conf?

Thanks for any and all help!
