Hi all,

I get this very annoying error for couple of days, without any clue what to do about it.
I recently bought Moneual 320 case, which comes with a FTDI based VL System (http://www.vlsys.co.kr but site doesn't open) VFD/IR panel; exactly the one described here. After the initial struggle with installing LCDproc, I finally managed to install (the default apt-get installed lcdproc doesn't work due to lack of ftdi support in HD44780 driver; I have compile from source) but now I'm getting Segmentation fault when try to start lcdproc.

Code:

root@htpc:/usr/local/etc# LCDd -f -r 5 -s 0

Built on Oct 21 2010, protocol version 0.3, API version 0.5

Looking in the dmesg, I see this is to do with libusb:

Does anyone know what to do next? Google didn't get me any where, so I thought if I use some of the expertise from here. I really hope someone has something for me. Any help of any kind very much appreciated. Cheers!!

Make a backtrace and send it to the lcdproc maintainers.

Already reported in the lcdproc mailing list - no such answer yet. How to reach the maintainers, anyway? Cheers!!

Dear mod,

Can you move this post to the LINUX specific section please? I think it best suits there. Cheers!!

backtrace sent to the lcdproc mailing list. Has anyone got any clue what's going wrong?
