[SOLVED] Latitude 5480: unable to boot Big Sur USB installer


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.

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