What is supposed to happen, is that usb_setup() sees that there is an ehci device and only runs ehci_setup() on the whole device. ohci_setup is not supposed to run from usb_setup() for that device at all. Then, if the ehci code finds a legacy device, it runs ohci_setup() from ehci_note_port() after it has configured all the legacy devices into legacy mode. This certainly used to work, I'll take a look. -Kevin _______________________________________________ SeaBIOS mailing list [email protected] http://www.seabios.org/mailman/listinfo/seabios
