I'm not sure I got this.
Do you mean disabling the "USB Injection" option in the installer?
I tried but nothing changed... Same errors, same screen as the screenshot.
Also what is an EC device name?
Sorry for the silly questions but I have no experience with hackintosh.
I tried both High Sierra and Mojave, with different USB sticks. Same error, similar screens.
The recurrent pattern (I think) is the incapability of power up USB ports, or at least the "insufficient power to enable this port" on both the OS
I tried to boot on my netbook the Olarila's High Sierra install disk following this guide https://Olarila.com/forum/viewtopic.php?f=50&t=8685.
This is what happens

This is what I tried\did:
Follow the guide
Change all the USB3 and the only one USB2 that I have
Check that I had my SATA deviced set to AHCI
(on BIOS) Disable Intel Fastboot technology
(on BIOS) Disable Graphic Scaling
What should I do?
