space_ghost:
 :D that's perfectly fine for me!

LambdaCalculus:
GodEater, have you heard any word from the eCos discussion list yet?

GodEater:
Nothing at all - I gave up.

LambdaCalculus:
Ah, crap. Back to the drawing board.

In the meantime, here's the output of lsusb -v on my laptop with the Karma attached:

Dave E:
Hello all. I hope this idea hasn't died out yet. I'd love to get rock box on my karma.

I wish I had more time to help. All I can really do is email people and pester them into submission. I've tried emailing DNNA, to no avail. However, I emailed Ecoscentric, the commercial arm of eCos, and got a prompt response as below. I'm going to give Red Hat a try next in the hope that something comes of it. I'm not holding my breath though.

Cheers,
Dave.

Hi Dave.

Unfortunately circumstances are against you. Your best chance of
acquiring the code is to politely persist with DNNA. Red Hat were under
no obligation to either publish the code online or make it available -
that is the responsibility of the authors - and I suspect the
contribution was lost within Red Hat after we left.

You could try and contact Red Hat who were the copyright holder and who
provided the license, but unfortunately I doubt you will get any
response or assistance from Red Hat in this regard as Red Hat no longer
have any interest in eCos. The current copyright holders, the FSF, will
be unable to help because this was all before their time.
