Acer PH517-51-72NU-US - External USB keyboard stops being recognized at each boot

Just received the Helios 500 as a replacement unit from Acer for my Predator 17 which has suffered 3 motherboard failures...yikes.  I use my laptop as a stationary unit 99% of the time, pluging in external monitors, keyboard and mouse.  Something strange is happening with my keyboard on the Helios 500 though...every time I boot the laptop it stops recognizing the external keyboard (SteelSeries Apex 350).  I have the latest engine installed from SteelSeries, drivers are current according to Windows Device Manager.  I get to the login screen and the keyboard is lit up, but not recognizing input. I'm forced to unplug the keyboard, plug it back in and voila, suddenly it's working again.  Every single time. Has anyone else had an experience like this?  It's driving me a bonkers...such a simple function should not be this difficult. Never had this issue with my Predator 17...

    I should have known you'd come asking...lol. Model is PH517-51-72NU-US.  An update on the issue...happens every time I boot, and also intermittently during regular use.  I'll unplug/plug at boot, keyboard will then be recognized, I use the system for an hour or two and suddenly the keyboard is no longer being recognized.  This is not accompanied by the typical USB disconnect sound, but when I unplug/plug it plays the connecting noise twice.  Very strange.  I've tried the keyboard on two other comps to make sure it's not the issue and it works perfectly on both.

    Another update...if I plug in an external USB drive it immediately causes the keyboard to no longer be recognized.  I unplug/replug the keyboard and it works for a minute or two, then once again stops being recognized.  Power is still getting to the keyboard as the key lighting is still active, but no input is accepted from the laptop.  It feels like a driver conflict, but everything is up to date as far as I can tell.  If anyone has input on finding/resolving potential driver conflicts, I'd greatly appreciate advice.  My goal at this point is simply to make it through a single day without having to unplug/replug the keyboard...ersh.

    Does this issue occur on other USB ports and with other devices?
