Please do a full test of the interface attributes (Class/SubClass/Proto)
whenever possible, this could be helpful in case the mfgr makes a device
with different interface layout but re-uses an already used vid:pid.
Both interfaces has attributes ff/00/00 so there is no reason for doing
a less accurate test.
