it would also be interesting to see output of ifstat from the working machine using the same usb nic that we know is working in the old one, and i guess this is also working inside of OSX on the new machine?

Yes, that is correct. All the nics I tried with ipxe are working when booted to OSX, and are also working to netboot the Mac to an Apple Netboot server (Deploy Studio in this case). Just not for PXE.

Yes, same build.

Hmm, when I tried to pxe-boot with one of the nics, I saw somewhere in the output something similar to "nii", but I don't remember which one that was. Will check on Monday...

so with something like:
Code:
make bin-x86_64-efi/ipxe--ecm--ncm.efi DEBUG=xhci
you will have usb drivers included and xhci debugging enabled, would be interesting to see ifstat from both the old and new machine with the same nic connected using this build.

one gotcha however is that any other usb device then the ones supported by ipxe will be disconnected, for example mass storage devices will no longer exist to the efi firmware if you exit out from ipxe and expect to continue booting from some other usb device.

OK, I'm gonna try that on Monday! Thanks very much for your help!
