I figure it might be helpful to report this somewhere as a data point:
I early-adopted El Capitan, running on a 2013 Mac Pro, and my USB PowerLinc (2448A7 rev2) ran without a hitch for months, then suddenly last night stopped. Restarting the interface and the local server did nothing. Reboot helped for about an hour before it stopped again. I think the trigger may have been related to power hiccups we experienced during last night's snow. The Mac is on a UPS, but some of the console log messages suggest the on-battery behavior might be a little conservative. That could be coincidence, though.
I keep the interface plugged into a long extension cable with a little unpowered 2-port hub at the end, to keep it away from potential RF interference from other hardware. Plugging the cable into a USB3 hub that is itself plugged into the back of the Mac, still no joy. Other devices plugged into that hub are still responsive. BUT I plugged the modem (with the extension cable) into one of the ports on the back of a Thunderbolt Display and it popped right up. Has been stable since. I'll post again if that changes.
