FTDI help needed

[Alex K. <ale...@gm...>]

Hello,

I've got a Digitus USB serial converter with an FTDI chip inside. I've been trying to use it with an Technisat TTS35AI remote but I can't.

OS:

Xubuntu 12.10

LIRC:

0.9.0

libftdi:

0.20

serial IR receiver:

serial dongle that came with a Technisat AirStar

FTDI device:

Mode 2 is giving me some output. But it's giving me for each key pressed multiple pulse and space infos. What seems strange to me is that pushing the same button creates a different output each time. (I have never worked with anything else but the devinput LIRC driver, so I can't really tell if that's okay.)

The parameter input=5 and input=6 are giving me this type of output. The others don't. Is it correct that there are 2 working inputs?

LIRC doesn't do anything with the lircd.conf for the TTS35AI. No error but also no success.

Therefore I tried to create my own lircd.conf. The program irrecord is opening the device properly but it's not creating any dots. But it keeps running as long as I keep pushing buttons. After I stop pushing the buttons on the remote irrecord quits after 10 seconds. So irrecord receives data but can't handle it. Using the --force option doesn't help either.

Any ideas?
