[Elecraft] Elecraft Mac People: KUSB Issue

[Joel Black]

I have turned off computer sleep on my Late 2012 iMac. It is set to “Never.” I do have my screen set to go to sleep. I have an add-on called Caffeine which, when selecting with my mouse, will allow me to either keep the display on or allow it to go to sleep. It’s my understanding that OS X runs its utilities during the wee morning hours and I don’t want to interfere with that (I could be wrong).

As for a powered USB-3 hub the HooToo hub works great: http://www.amazon.com/gp/product/B00FR795WA?psc=1&redirect=true&ref_=oh_aui_detailpage_o04_s01 <http://www.amazon.com/gp/product/B00FR795WA?psc=1&redirect=true&ref_=oh_aui_detailpage_o04_s01>

I do *not* try and run my external sound card through it.

73,

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?
