Ok, it looks like this is the same PCI configuration space parsing bug 
that we're seeing in -current.  I have *no* idea what's causing this yet.

If you're feeling inspired, can you print the value of cfg->nummaps at 
the beginning of pci_add_resources in sys/pci/pci.c ?  The value we're 
interested in is the one that would be printed just before the USB 
controller's output.

Thanks!
