So more testing. I put 3 of these on a Win 10 Home x64 machine (Clean install, literally NOTHING on it) that has a 7 gen intel I-7 and seeing 55% CPU usage on that machine while running CGminer with 3 compac-f units
...
Is this high CPU utilization (55% of 7gen i-7) normal for just 3 units?
You have the Zadig USB driver loaded? I'm running 1 F at 425MHz along with 2 Newpacs on a very old Lenovo mini-PC -W7, dual-core Atom, 2GB memory and they cruise along nicely, CPU Meter reports 15% usage.
