I'm still just having a hard time understanding the overall "how to get a path out, given a lsusb listing". I started reading this: http://www.networkupstools.org/doc/2.2.0/hid-subdrivers.html Is this actually relevant to me? It seems that if someone else has done most of the work for HID power supplies, I'll have more luck beginning with that? > >Overall, I'm just confused as to what's going on or how to progress > >and > >make this work.

At least to start, I just want to read the current state of the PSU. Saliently, at least to start, I just want to be able to figure out whether the ignition is connected or not, and if not, how long until it actually shuts the whole system down. I figure that once I see *something* everything else is in the realm of figuring out the device-specific hoojimajiggery. I'm still just at the point where I want to see *something*. Thank-you so much for your time and explanations, they've really been helping me.
