Administrators Hervé Posted August 25, 2016 Administrators Share Posted August 25, 2016 Try to unplug/replug your USB key or replug it in a different port. Link to comment Share on other sites More sharing options...

Administrators Hervé Posted August 25, 2016 Administrators Share Posted August 25, 2016 Did you try all USB ports when attempting to boot your USB installer? Sure, you may need to use a USB injector kext, but you need to identify your USB ports 1st... You could try the USB injector I posted in my E6220 EC guide; it may bring life to some if not all your USB ports. It'll require that you also use the same names in your DSDT for EHCx devices + same SMBIOS plist. Otherwise, adjust the USB injector kext according to your system boot settings.
