[Elecraft] Elecraft Mac People: KUSB Issue

[David Ahrendts]

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.

Trying to keep MacLogger connected to the K3S via it’s KUSB for several days at a time (like Labor Day weekend). It appears to get kicked off for inactivity as a power drain which requires (I know, poor me!) re-starting the Mac Mini to re-initialize the USB port with the KUSB. Not a big thing, but maybe there is a way to refresh the USB devices connected (a Mac issue). Anyone?
