No; others include Apple iSight cameras (the built-in USB variants), bluetooth devices (usually USB too), Keyspan serial adapters (usually USB), a bunch of stuff in drivers/media/video/, some non-USB network adapters, and some adaptec and qlogic sci drivers. It seems that most USB devices require firmware no matter what type they are. Beyond that: probe: scsi/qla2xxx, net/myri10ge, scsi/aic94xx, net/spidernet open: serial/icom Dan - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
