Hi David,
first, please keep the list posted. It's also probably better to use
the
users list, instead of the developers one...

Arnaud,
thanks for your reply. I am using @nut 2.6.1 according to macport.
It seems that the problem i am having is permissions related. Here
is the
output I get…
sudo blazer_usb -a trust-ups -DD -u root

I am currently running everything as myself (normal user), but as
you see I
get the error even with the -u root option.
Incidentally I get *exactly* the same result without that option so
perhaps
i am barking up the wrong tree.
I've been googling like crazy, but I can't find any OSX specific
instructions that help much…
Charles may have an idea on that, since he's somehow our Apple expert.
I would like to know which libusb version is used (ie, 0.1 or 1.0).
Just going through some NUT emails and saw this.
David: I use Fink instead of MacPorts, so I'm not sure how they handle
libusb. NUT uses the 0.1 API, but that can either be provided by
libusb-0.1.x (currently 0.1.12) or by the compatibility layer of
libusb-1.0. Can you check on that version number?
Also, OS X has the concept of security contexts, and I think that USB
devices are "owned" by processes in the console context. Are you
starting the NUT driver from a console context (e.g. Terminal.app
while logged in), versus from a SSH session?
