Documentation/usb/wusb-cbaf Documentation/ABI/testing/sysfs-class-uwb_rc-wusbhc Documentation/ABI/testing/sysfs-wusb_cbaf Documentation/ABI/testing/sysfs-bus-usb The basic set of steps to set up a WUSB connection are: 1. Start the wireless channel by storing a CHID value to the host controller's wusb_chid sysfs attribute. 2. As child devices connect, verify that the value read from their wusb_cdid sysfs attribute matches a known device. 3. If the device is known, set the device's wusb_ck attribute to the private CKEY value for that device in order to authenticate it. 4. Once authenticated, set the authorized attribute to 1 to allow the usb core to enumerate the device. Once that is done, the device should look like any other USB device in the system. Hope this helps, Thomas -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
