Re: 1-wire to USB converter that can use 1820s directly

Ahh! I see you've made my killfile in a previous incarnation. Had I
recognized the name I would not have wasted my time.

Turning once again to your initial post...

1. You asked for "a fully assembled USB/1-wire converter". The DS9490R meets
your criteria.

2. You asked for "a decent driver that can be used from VBA from Access or
Excel etc." Maxim has two 1-wire APIs that are copiously documented at...

Whether or not they will run afoul of the FCC's anti-indecency crusade, I
can't say. I don't do 1-wire so am not interested in delving deeper into the
nuts and bolts. The COM version can be used from VB Script so it should be
usable from VBA.

There's a link on the above cited page to a "developers list" which is
probably where you should be spending your time rather than wasting the time
of others here. If you're unable to make use of the APIs yourself, maybe you
can find a reference to an Active-X control or find someone willing to
create one via the developers list.

Now to add this new identity to my killfile.
