Do you know how to check USB2.0/USB3.0 in Grub2? I am trying to prove it.
not sure. GRUB has an `lsmod` command, if that lists something with ehci or xhci, that might give a clue. Actually, I would just grep the source code. In my current GRUB master checkout, `git grep -i xhci` returns nothing.
But another question is then why EHCI driver cannot work when running with Coreboot on Denverton-NS platform? Is that due to only xHCI controller in Denverton-NS?
Yes, an EHCI driver can't work with an xHCI controller (and Denverton has xHCI only, AUIU). Nico -- coreboot mailing list: [email protected] https://mail.coreboot.org/mailman/listinfo/coreboot
