I have merged the subsystem and idVendor checks in a single rule, and
fixed the interface number based properties to again use the hidden
.MM_USBIFNUM property. Looks like I really messed up the rules and for
some reason I wrongly tested that stuff, sorry for that. Please retest
with git master and let me know if you're still experiencing issues.

That said, I think we could make the rules much simpler and safer by
using udev's built-in properties like ID_VENDOR_ID or
ID_USB_INTERFACE_NUM, because those are already set in the actual port
device so we don't need to mess around with matching against parent
device attributes with ATTRS{}. I'll likely prepare a patch and
suggest that in the mailing list.
