It works!

No crash, and my little Z-Wave test software works as well.

I just turned on some lights via Linux for the first time...

Well, I've thrown together a document with some of my sniffer logs and analysis of them.

I'll try it out later today when I get back home.

Thanks!

Great, I'll be happy to test it (although not on my router/asterisk machine this time I think  ;) ).

I'm working on my own code to talk to a Z-wave controller (ZCU201), the result will hopefully be a small C library with some documentation.

I'm using a combination of the LMCE code, the Zensys docs you have also found, and some reverse engineering to figure things out...

One thing I'm curious about is the actual legal status of the Z-wave code in LMCE. It couldn't have been written without access to information under NDA with Zensys right? Further more, some of the header files still have Zensys copyright notices...

I did some munching to the spcp8x5 code and managed to compile and load the module on 0704. If somebody feels like sending me a ZCU201...


Thanks for the patch, I got the module to compile for my kernel (2.6.21.5) and it loaded.

However, when I loaded the module with my ZCU201 plugged in, this is what I got in my kernel log:

I didn't expect the driver to register 14 devices :)

I'm not much of a kernel hacker, so I have real idea how to debug this...

Worse things happened when I tried actually opening the device (ttyUSB0) in my test program...

etc. etc.

I had to reboot the machine.
