Re: 1-Wire Demo Kit & Linux

["Stuart Grimshaw" <stuart@xxxxxxx>]

I had this exact problem with mine. If you can try it on a windows PC, with
the software on the disks and it should work fine. Then try it on your
Linux
box, and hey presto! Works like a charm.

BTW, I'm using the Digitemp software not any of the examples that come with
the kit, as they are all for the 9097U type adaptor.
http://www.brianlane.com go for
v1.3 which will work with the supplied
adaptor.
