Many thanks for the half-dozen direct responses off list. Most of you run a powered USB hub for the KUSB (or several). May I ask what type/brand powered hub are you successfully using with your Mac device for the KUSB or multiple KUSBs?
It appears the chip in the KUSB can be interpreted as a real power hog, and the Mac Mini, MacBook Pro, iMac will protect against unusual drain. It just shuts off the USB port after a little warning. A powered hub would certainly remove that load from the Mac. I will also admit to being one of the million or so Mac beta testers and we’re currently on OS X El Capitan beta Version 10.11 (15A278b). And believe me, there have been/are plentiful Mac sleep-wake issues before they finalize.
