Thank you, Daniel! 1. Detection seems to work 2. 1-wire search fails after 27 of 64 steps, Not sure why. 3. Clearly a failed directory listing is getting cached -- unrelated error.
I'll make some changes to see if we can figure out why the search is failing. It seems like a timing, hardware or driver problem, really. Paul On 5/23/06, Daniel Höper <[EMAIL PROTECTED]> wrote:
