Hi, Using the usbconfig utility in 8 stable and 9 current, you can set the configuration to 255 which means unconfigured and then 0 for the root HUB. For non-root HUBs you can BUS-reset the devices usbconfig -d X.Y reset or set_config aswell. There is also a power_off command, but your device might not come back after that. --HPS _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
