Strange that
@bmoney is still suffering freezes but not you and
@jleahy2 ?
Hi,
I wanted to report back after a lot hours of working without any freezes and experimenting with different devices on the MB ports to see what wreaked havoc.
The Inateck card was a viable solution but
@ziggenpuss ' fix was also basically correct (eliminating unused ports didn't help but isolating USB devices on a powered hub was the fix).
I'm sorry if I ever doubted you @ziggenpuss - I didn't check my setup correctly. I'm 99% sure that my freezes were the result of a passive (unpowered) hub that I thought was powered. (Doh!! Such common sense. Arrrrrrg.....) My kensington expert mouse, iLok, korg nano and keyboard were on a cheap hub which was buried in a mess of cables and, lo and behold, once I eliminated it and grabbed a good old 10 port Plugable USB2 powered hub for HS9, I had no issues whatsoever. (These can be had on ebay for around 15 shipped):

Maybe there is something in Mojaves's internal USB drivers that freaks out if a port power requirement is exceeded which is much less robust then previous OXs' or Win10's. Maybe some systems are more sensitive then others depending on power supplies or MB quirks.
@CaseySJ, If you are going to add a USB best practices spoiler I would suggest making sure all USB1/2 devices on the USB 2 ports and getting sufficient power from a powered hub and/or trying a different powered hub if freezes persists. If all else fails s PCI card should be a fix.
SUPER BIG PROPS to everyone who chimed in on this. Thanks for your help and patience. I knew it was probably something simple and it was. The system is working beautifully and I feel like a bit of an idiot for not doing a more thorough check of my USB mess which (was never an issue with my mac pro).
ALSO, @CaseySJ. You are one of the most helpful people of all time. Not only have you provided one of the most detailed build instructions ever, you've tirelessly helped and guided so many of us with fixes and troubleshooting- In the end helping us save s*&tloads of money to have the best tools we can build. If you are comfortable PMing me a email or donation/payment methodology I would be very happy to send you some money as show of appreciation. You can buy beers or whatever you want with it. If it's not in violation of any forum rules
I also would encourage anyone else who can swing it to show their gratitude by throwing @CaseySJ some dinero. THANK YOU
