lspci tells you vendor and device id. These IDs need to be told to the
driver. Because the uhci driver uses:
static const struct pci_device_id uhci_pci_ids[] = { {
/* handle any USB UHCI controller */
PCI_DEVICE_CLASS(((PCI_CLASS_SERIAL_USB << 8) | 0x00), ~0),
.driver_data = (unsigned long) &uhci_driver,
}, { /* end: all zeroes */ }
};
I think your device is just broken (and doesn't tell it's a USB host).
If you think it's really driven by uhci (and not by ohci), then stick
your device IDs into that table, or add those dynamically by echo'ing
them to /sys/bus/pci/drivers/uhci_hcd/new_id. You need sysfs mounted to
/sys, though.
