Hello Grant,

I've had similar device issues with hardware attached
to the pci bus. I found this obscure command that
updates the master list of pci device "id" on a gentoo system:

/usr/sbin/update-pciids 

This may help:

Maybe there is such a script for usb buss related numbers,
or the ones posted for your devices need updating?

It's a shot in the dark, but may give you and idea
on what's misaligned with that particular device?

hth,
James
