Hi, I tried GRUB EHCI driver inside VirtualBox (v. 4.1.18) - and it works.
So, why GRUB EHCI doesn't work in VMware ? I don't know. I have only some probably stupid idea - maybe VMware virtualization has built-in some optimization which prevents correct operation of EHCI in poll mode (without interrupt)...
