        * bus/usb/ohci.c (grub_ohci_pci_iter): Check that programming
        interface is OHCI.  Add grub_dprintf for symmetry with
        bus/usb/uhci.c.
        * bus/usb/uhci.c (grub_uhci_pci_iter): Check that programming
        interface is UHCI.  Add interf variable for programming
        interface.  Print interface with class/subclass.
