USB Driver uhci.c legacy mode

Hi all,
I am using grub2 uhci.c usb driver for testing new hardware, on some occuisions the UHCI signature test fails (can be found on the PCI iteration routine), the driver thest if the controller founded by PCI has a signature as uhci should have (0x0c0300), on some of my new hardwares the signature is as EHCI (usb 2.0) means 0x0c0302, if i change the signature that the driver searches the rest of the driver fails, probably because i need to activate a legacy bit in the configuration register in the EHCI Controller.
i have searched EHCI Specs for legacy mode and could not understand how to configure legacy mode... and i hope some of you guy could help me.
