Peter,

thank you for the very detailed data.
Unfortunately, I don't see any explanation for what you are experiencing.

I came up with some things with which you can try to experiment:

1. Boot with hw.pci.usb_early_takeover="0" in loader.conf.

2. Comment out the following line in sys/dev/usb/controller/uhci_pci.c:
pci_write_config(self, PCI_LEGSUP, PCI_LEGSUP_USBPIRQDEN, 2);
