System Administration Commands wusbadm(1M) NAME wusbadm - administer wireless USB hosts and devices SYNOPSIS wusbadm list [-h | -d] [-o field[,...]] wusbadm associate [-h host-id] [[-c [-f]] | -n] [-o] wusbadm remove-dev [[-d dev-id] | [-h host-id]] [-f] wusbadm remove-host [-h host-id] [-f] wusbadm enable-host [-h host-id] wusbadm disable-host [-h host-id] DESCRIPTION The wusbadm command provides a command line interface to administer wireless USB hosts and devices, including listing hosts and devices information, associating the host with the device, removing host or device information from the system, and enabling or disabling hosts. Before connecting a wireless USB device to a host for the first time, a user needs to set up the association information between them by run- ning the wusbadm associate subcommand. Following this, the user can connect or disconnect the device by simply turning on or off the device radio (perhaps a button on the device, depending on the manufacturer). The device radio's turning on and off are analogous to the hotplugging of wired USB devices. The association information created by the associate subcommand is maintained in the non-volatile memory of the device and the host. On the host, it can be removed by the remove-dev or remove-host subcom- mands. On the device, it can be overwritten by another association. For a device is associated with multiple hosts, the way that the device prioritizes or updates its multiple records of association depends on the manufacturer. Each wusbadm subcommand operates on one of the following objects: host-id A two-digit number (in the range from 01 to 99) that uniquely identifies a wireless USB host on a system. It is generated when the wusb service (see NOTES section) is successfully enabled and finds the host instance for the first time. The number is main- tained until removed by remove-host subcommand. dev-id A five-digit number that uniquely identifies a wireless USB device associated with a wireless USB host. The first two digits are the host-id of the wireless USB host with which the device is associ- ated. The last three-digit number (in the range from 001 to 999) is used to differentiate devices associated with the same host. In the five-digit number, the first two digits and the last three are sep- arated by a dot. dev-id is generated during the device association process. It is maintained for the device until removed by the remove-dev subcom- mand or until updated by another association between the same host and device. SUB-COMMANDS The following subcommands are supported. Except for the list subcom- mand, each subcommand displays subcommand-specific usage information if you run it without any options or operands. list [-h | -d] [-o field[,...]] List wireless USB hosts and devices on a system, displaying the ID, state, and type for all hosts and devices. By default, list will list all hosts and devices and all fields. Each host and its devices will be displayed as a group. This subcommand supports the following options. -o field[,...], --output=field[,...] A case-insensitive, comma-separated list of output fields to display. The field name must be one of the fields listed below, or the special value all to display all fields. By default (without -o), list displays all fields. ID The host-id or dev-id. TYPE The host or device types. For host, the types include whci (on-board host) and hwa (hot-pluggable host). For device, the types include kbd, mouse, storage, printer, dwa (wireless USB hub), audio, video, and so forth. STATE There are the following states for the host: enabled The host is ready to work or is already working, including performing association, connecting devices, performing data communication, and so forth. disabled The host is not ready to work with any devices and no devices are connected to the host. It might be stopped by a disable-host subcommand, or the host might not be available because it is physically unplugged or because of a driver detach. disconnected The host is not attached to the system. An hwa device is in this state after it is unplugged from the USB port on the system. There are the folllowing states for the device: connected The device is connected with a host and ready to be opened, or it is already opened and working. By default, the device tries to get into this state after the association is complete and its radio is turned on. disconnected The device is not connected to a host or not ready to be opened yet. The device might be in this state because its radio is out of range, power is off, hard- ware problems, and so forth. -h, --host List the wireless USB hosts only. -d, --device List the wireless USB devices only. associate [-h host-id] [[-c [-f]] | -n] [-o] Designate the host to start an association process. Association is the initial step before a wireless USB device can be connected with a wireless USB host. There are two association models: Cable association A user connects the device and host with a USB cable first, and then run this subcommand to designate the host to setup the association information with the device. After the association is in effect, the cable is no longer needed in the subsequent connections between the same host and the device. Numeric association A user turns on the device radio and runs this subcommand to designate the host to talk to the device. A short number is then displayed on both host and device. The user compares the values of the numbers and confirms on both the host and the device. Following a successful association, the associated USB host and device are able to proceed with the wireless connection process. By default, the association information will be kept both on the host and the device until it is removed or overwritten. If there are multiple devices available for association, this sub- command will list all of them, enabling a user to choose among them. This subcommand has the following options. -h host-id, --host host-id Specify the host for which the association will be done. If this option is not specified, this subcommand lists all enabled hosts for users to choose. -c, --cable Start the cable association process. A user plugs the wireless USB device to the host and runs the associate subcommand with this option. -n, --numeric Start the numeric association process. This subcommand prompts the user to compare the number displayed on the host and the device. If neither of the preceding two association model options (-n or -c) is specified, this subcommand prompts the user to specify one of the following association model options. -f, --force Start the cable association process. A user plugs the wireless USB device to the host and runs the associate subcommand with this option. -o, --onetime Indicate that this association is for a one-time connection. That is, after the association, if the device is connected and then disconnected, the association information for this device will be removed from the host system. A user would need to per- form another association for the next connection. remove-dev [[-d dev-id] | [-h host-id]][-f] Remove the association information of the wireless USB device from the system. After the removal, the device cannot be connected with the host until the user runs the associate subcommand again, for the host and device. This subcommand has the following options. -d, --device=dev-id Remove the association information of the wireless USB device specified by dev-id. -h host-id, --host=host-id Remove the association information of all the wireless USB devices associated with the host specified by host-id. -f, --force Perform the removal without asking for confirmation. If the device is being connected with the host, then this subcommand will force it to disconnect. remove-host [-h host-id] [-f] Remove the host information from the system, including host-id and the association information of all the devices associated with the host. This subcommand is used most often for removing the temporar- ily used hot-pluggable wireless USB host, for example, a hwa don- gle. The host can be brought back by being re-enumerated, for exam- ple, physically hot-plugging a hwa dongle. The host-id will then be updated and no device association information can be restored. It is not recommended to remove a on-board host. This subcommand has the following options. -h host-id, --host=host-id Specifies the host-id to be removed. -f, --force Perform the removal without asking for confirmation. If there are one or more devices connected with the host, then force them to disconnect. enable-host [-h host-id] Take the host to the enabled state. By default, the host is in the enabled state. This subcommand has the following option. -h host-id, --host=host-id Specifies the host-id to be enabled. disable-host [-h host-id] [-f] Take the host to the disabled state. The host-id and all the asso- ciation information of the host are maintained. Issuing an enable- host subcommand brings the host back to the enabled state. This subcommand has the following options. -h host-id, --host=host-id Specifies the host-id to be disabled. -f, --force Perform the disable operation without asking for confirmation. If there are one or more devices connected with the host, this option forces them to disconnect. EXAMPLES Example 1 Listing All Hosts and Devices The following command lists all wireless USB hosts and devices. # wusbadm list 01 enabled hwa 01.001 connected mouse 01.002 connected kbd 02 enabled whci 02.001 connected printer 02.002 disconnected storage 03 disabled hwa 03.001 disconnected storage 03.002 disconnected dwa Example 2 Associating to a Device Using Cable The following command associates a device to a specific host (host-id 01), using the cable association approach. # wusbadm associate -h 01 -c Associate a device with host (01) via cable. Continue (yes/no)? Example 3 Removing a Device's Association The following command removes a device's association information from the host system. # wusbadm remove-dev -d 01.002 Remove the information of device (01.002) from system. This device can not be connected with the host until it is associated again. Continue (yes/no)? Example 4 Removing Associations for All Devices The following command removes the association information for all devices associated with a specific host. # wusbadm remove-dev -h 02 Remove the information of all the devices associated with host (02) from the system. All the devices associated with the host cannot be connected with it until they are associated again. Continue (yes/no)? EXIT STATUS The following exit values are returned: 0 Successful operation. 1 Error: the operation failed. For example, a device failed to asso- ciate with a host. 2 Usage error.
