Here are couple of things I tried.

1) Changed the USB cable.  Same problem
2) I put an old CyberPower CP550SL w/USB&SERIAL and it recognize it right away via the USB port
I don’t know if that will give you any insight or eliminate certain things with the Tripp Lite SMART1300LCDT or not.

What I mean is that you can't have more than one usbhid-ups process talking to the same UPS at one time - regardless of whether they write a PID file. In the case of running with "-D", you would need to double-check for any in the background (and there was a PID file named usbhid-ups-upstl1300.pid). "ps auxww|grep [u]sbhid-ups" should show only one driver in either case.

Still looking into the altsetting issue. I would have to shuffle a few machines around to get a copy of 10.2 running on a box that isn't being actively used for anything else, but maybe there is something in their source control logs.
