My steps so far:
Set up Catalina install USB exactly according to Plain Vanilla guide.
Disconnect my Windows drive in PC, so that only the empty Hard Drive is connected to Motherboard.
Boot to USB, select Install Catalina option. BIOS set to UEFI, Safe mode Off.
Always get stuck at the same IOconsoleUsers: GIOScreenLockState point.
Tried -radvesa, -radoff, nv-disable=0 boot options (separately), and disabling BIOS virtualization (vt-d) -> NO luck. This from the top search result https://www.reddit.com/r/hackintosh/comments/b5a6ry/ioconsoleusersgioscreenlockstate_3_blackscreen/
Screen pics attached. Here are the last couple of lines that could be important:
GTrace synchronization point 4
Adding ADGP mode validate property
hmm.. mismatch sizes 3100 vs 20
IOConsoleUsers: time(0) 0->0, lin 0, llk 1,
IOconsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0
Please give me some ideas what else might work. Thank you.

I have just re-made the Catalina installer, with the updated OS. It could not install from it, like it could not copy. Then I have tried to reinstall Mojave, it worked pretty cleary last year the exact pen drive. It failed as well, saying something like: not package found, contact the system administrator. I was able to boot from USB pen drive Linux and install Windows from DVD. But no macOS from the pen drive, even from what worked fine before. I have reseted the BIOS several times, no succes. The first sign of something wrong was this: When I first tried to boot Catalina, it said something about BIOS (BIOS, not UEFI) reset and enter setup. I hapenned several times on my attempts. If something screwed in my hardware? The USB ports? The BIOS perhaps?
I purchased two of these Sipolar 10 port USB 3.0 hubs with the thought I'd be able to plug in 20 iPads to do software restores simultaneously, but I only can get 12 to be recognized at any one time. Both hubs function properly with 10 iPads plugged in to each at once, but as soon as I connect both hubs I get a max of 12 iPads recognized by the OS. We're using Apple Configurator 2 to restore iPads, and I have a separate older/slower 32 port USB 2.0 charge/sync hub that works fine with all devices plugged in.
I'm using a 2014 Mac Mini 7,1 running 10.15.3. I've tested the hubs with a few difference Macs and OS's and have had the same issue. From what I can tell these hubs use a RealTek USB chipset, but no drivers are offered by Realtek for them.
I attempted to daisy chain them (not ideal) and still have the same issue. Has anybody run in to a similar issue using identical USB hubs connected to individual ports on a Mac?
