LIRC-0.9.1: Remote not working, scancodes, config issues

Hi,

I'm using arch (kernel 3.16.0-2-ARCH #1 SMP PREEMPT x86_64 GNU/Linux), a TechnoTrend USB IR Receiver and my custom remote (not covered by existing configs). I installed lirc and lirc-utils via testing repo (lirc-0.9.1). My problem is that I can access my device, but irw gives me no output at all.

At first some outputs:
ir-keytable:

Found /sys/class/rc/rc0/ (/dev/input/event17) with:
	Driver ttusbir, table rc-tt-1500
	Supported protocols: NEC RC-5 RC-6 JVC SONY SANYO LIRC other 
	Enabled protocols: RC-5 
	Name: TechnoTrend USB IR Receiver
	bus: 3, vendor/product: 0b48:2003, version: 0x0101
	Repeat delay = 500 ms, repeat period = 125 ms

output of "ir-keytable -t" for numbers 1-6 on my remote:

I start lirc manually with

lircd --driver=devinput --device=/dev/input/by-id/usb-TechnoTrend_AG_TT-USB_Infrared_Device-event-ir BlackFlatOne -n

After starting lirc, I start irw, but I get no response at all when pressing buttons on my remote.
I already tried a

cat /dev/input/by-id/usb-TechnoTrend_AG_TT-USB_Infrared_Device-event-ir

(lirc and irw not running, of course) and this gives me cryptic symbols when pressing buttons on my remote, so the IR receiver doesn't seem to be the problem.
I'm wondering if the scancodes in my config are ok for a devinput-device, because the latest "official" lircd.conf.devinput looks like that:

                KEY_6                   7
                KEY_7                   8
                KEY_8                   9
                KEY_9                   10
                KEY_A                   30
                KEY_AB                  0x196
                KEY_ADDRESSBOOK         0x1ad
                KEY_AGAIN               129
....

So I'm wondering about the different lengths of the keycodes (e.g. 0x0d vs 0x1ad -> 2 vs 3 digits).

Can anyone help me out with this issue ?
Am I missing something ?
How do I have to format the scancodes/keycodes the correct way for version 0.9.1 ?
