Yeah, something still seems wrong here.  In cases where the device
uses one of the Empia generic USB ids, you need to have either an i2c
hash entry of an eeprom hash entry.  That's how it knows which device
to associate it with in those cases.

Did you try this patch?  If so, can you send the full dmesg output
after connecting the device?
