Recommended Posts

Hello all,

 

I followed the latest OpenCore guide for Skylake laptops and upon boot to install from USB, I get an error and the system stops:

AppleUSBHostPort::createDevice: failed to create device (0xe00002bc); attached boot log

 

OpenCore 0.7.3

Installing Big Sur

Latitude 5480 w/ Intel Core i5-6300U Skylake HD520

 

Thank you.

Thank you both! Disabling XhciPortLimit allowed booting and installed Big Sur. Everything seemed to have installed well except trackpad (Alps l2c) and audio (Realtek ALC3246). Any tips on how to proceed?

Got sound working by following the Post-Install guide "Fixing Audio"; for others that have the same hardware:

PciRoot(0x0)/Pci(0x1F,0x3)

     layout-id <15000000>

 

Last hurdle is the Alps trackpad...I just need basic functions for now, thanks.
