This looks likely to be the culprit -- uhci attach failed, but left it
in a state not expected by uhci detach.

This message comes from the x86 pci_intx_alloc when pci_intr_map
fails:

    448 	if (pci_intr_map(pa, handle) != 0) {
    449 		aprint_normal("cannot set up pci_intr_handle_t\n");
    450 		error = EINVAL;
    451 		goto error;
    452 	}

Can you share the output of the following commands?

# pcictl pci0 dump -d 26 -f 0
# pcictl pci0 dump -d 29 -f 0

Perhaps that will provide a clue about what's wrong with the device's
PCI interrupt mapping.

Is this problem new?  Does it occur with, e.g., the 9.3 image, or 8.2,
or any other older versions?
