The exception list means "usb_device_id entries for specific devices that are known to need the workaround." There are just two such entries. There isn't even a separate list. So maybe we just have a nomenclature problem, and we could simply be calling this a "white list" instead of "exception list". The other possible meaning of whitelist (all devices that *don't* need the workaround) is unthinkable, as that would be a huge list and much more prone to be unmanageable than what we've got now. -- Rob Gardner <robmatic@xxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
