- USB hardware-specific commands for cfgadm
/usr/sbin/cfgadm [-f] [-y | -n] [-v] -c function ap_id...
/usr/sbin/cfgadm -f [-y | -n] [-v] [-o hardware_options]
-x hardware_function ap_id.../usr/sbin/cfgadm -v [-a] [-s listing_option]
[-l [ap_id | ap_type...]]/usr/sbin/cfgadm -v -h [ap_id]...
The Universal Serial Bus (USB) hardware-specific library /usr/lib/cfgadm/usb.so.1 provides the functionality for administering USB devices via the cfgadm(1M) command. cfgadm operates on attachment points. For details regarding attachment points, refer to cfgadm(1M).
For USB administration, the only attachment points supported are the ports of hubs attached to the USB bus.
Attachment points are named through attachment point IDs (ap_ids). The USB bus is hierarchical, so the ap_ids are as well. USB hubs have ports, numbered from 1 to n. All USB ap_ids consist of a string of the following form:
usbN/A[.B[.C[...]]]
where
|
For example, the first port on the root hub of USB controller 0 (the only controller), has a logical ap_id:
usb0/1
Similarly, the second port on the first external hub plugged into the first port on the root hub of the first USB controller has a logical ap_id:
usb0/1.2
For example, if the ap_id is usb0/1.4.3.4, it represents port 4 of the hub plugged into port 3 of the hub plugged into port 4 of the hub plugged into port 1 of the root hub of the first USB host controller on the system.
example# cfgadm -l Ap_Id Type Receptacle Occupant Condition usb0/1 USB-hub connected configured ok usb0/2 unknown empty unconfigured ok usb0/1.1 USB-storage connected configured ok usb0/1.2 unknown empty unconfigured ok usb0/1.3 unknown empty unconfigured ok usb0/1.4 USB-device connected configured ok
USB2.0 chips have one EHCI host USB2.0 host controller and a number of companion USB 1.x host controllers (either OHCI or UHCI host controllers).
When a USB2.0 device has been plugged in, it shows up on the EHCI logical ports which might not have a 1 to 1 mapping to external physical port numbers on the system. When a USB1.x device is plugged in, the EHCI host controller reroutes the device to a companion host controller and the device shows up on the companion's logical port number.
The mapping of logical port numbers to physical port numbers can get quite complicated. For example:
% cfgadm Ap_Id Type Receptacle Occupant Condition c0 scsi-bus connected configured unknown usb0/1 usb-mouse connected configured ok usb0/2 usb-kbd connected configured ok usb0/3 unknown empty unconfigured ok usb0/4 usb-hub connected configured ok usb0/4.1 unknown empty unconfigured ok usb0/4.2 unknown empty unconfigured ok usb0/4.3 unknown empty unconfigured ok usb0/4.4 usb-storage connected configured ok usb1/1 unknown empty unconfigured ok usb1/2 unknown empty unconfigured ok usb1/3 unknown empty unconfigured ok usb2/1 unknown empty unconfigured ok usb2/2 usb-device connected configured ok usb3/1 unknown empty unconfigured ok usb3/2 unknown empty unconfigured ok usb3/3 unknown empty unconfigured ok usb3/4 unknown empty unconfigured ok usb3/5 unknown empty unconfigured ok
In this example usb0 is the onboard USB 1.x host controller. usb1 and usb2 are companion OHCI USB1.x host controllers and usb3 is an EHCI USB2.0 host controller.
The following table shows the somewhat confusing routing for this USB2.0 chip:
logical port number physical port number
------------------- --------------------
usb1/1 internal port 1
usb1/2 external port 1
usb1/3 external port 3
usb2/1 internal port 2
usb2/2 external port 2
usb3/1 internal port 1
usb3/2 internal port 2
usb3/3 external port 1
usb3/4 external port 2
usb3/5 external port 3Unfortunately, the exact routing can often only be determined by experimentation.
The receptacle states for attachment points at the USB port have the following meanings:
USB port is powered on and enabled. A USB device is plugged in to the port. The device is logically connected to the USB bus.
USB port is powered on and enabled. A USB device is plugged into the port. The device has been logically disconnected from the USB bus (using the cfgadm -c disconnect command).
USB port is powered on, but no device is plugged in to it.
The occupant states for devices at USB port attachment points at the USB port have the following meanings:
The USB device at the USB port is configured and usable by Solaris.
The USB device at the USB port was explicitly off-lined using cfgadm -c unconfigure, or was not successfully configured for use with Solaris, for example, having no driver or a device problem.
The attachment point conditions are:
Normal state - ready for use.
Not used.
Not used.
The user has physically removed a device while an application had the device open (there might be outstanding I/O). Users need to reinsert the same physical device and close the application properly before removing the device again. The port cannot configure other inserted devices until this is done.
If the original device cannot be reinserted into the port, see the Oracle Solaris Administration: Common Tasks for instructions for clearing this attachment point condition.
Not used.
A USB device can be hotplugged or hotunplugged at any time, and the system detects the event and takes the appropriate action.
It is not necessary to transition a receptacle to the disconnected state before removing its device from the USB. However, it is not recommended to hot-remove devices currently in use (such as removable disks currently opened by a volume manager or some other application).
cfgadm defines several types of operations. These operations include invoking configuration state changes (-c), invoking hardware-specific functions (-x), and obtaining configuration administration help messages (-h).
If any of these operations fail, the device and attachment point might not be in the expected state. Use the cfgadm -l command to display the device's current status.
All other options have the same meaning as defined in cfgadm(1M).
The following options are supported:
The following generic commands are defined for the USB hardware specific library. The following configuration state change operations are supported:
If there is a USB device plugged into the port, this command attempts to configure it and set everything up so that it is usable by Solaris. This command does an implied connect (reverse of disconnect) if necessary. This command accomplishes nothing, and returns an error message, if the device at that port is already configured. After successful execution of this command, the device is ready for use under Solaris.
Performs an unconfigure on the ap_id (if it is not already unconfigured), and then transitions the receptacle to the disconnected state, even though a device is still be plugged into the port. Issuing a cfgadm -c configure, or physically hotplugging the device, brings the device back to the connected receptacle state, and to the configured occupant state, assuming a driver can be found and there are no problems enumerating and configuring the device.
Makes the device plugged into the port unusable by Solaris (offline it). If successful, cfgadm reports this ap_id's occupant state as unconfigured. Issuing a configure to the ap_id (if successful) brings its occupant back to the configured (online) condition, as it physically hotplugging the device on the port.
Not supported.
USB specific help can be obtained by using the help option with any USB attachment point.
The -l option works as described in cfgadm(1M). When paired with the -v option, the Information field contains the following USB-specific information:
Mfg: manufacturer string (iManufacturer)
Product: product string (iProduct)
NConfigs: total number of configurations the device supports (bNumConfigurations).
Config: current configuration setting in decimal (configuration index, not configuration value).
The configuration string descriptor for the current configuration (iConfiguration)
See the Universal Serial Bus specification for a description of these fields.
Hardware options are only supported for the hardware-specific command, -x usb_config. See the description of that command below for an explanation of the options available.
Attachment points of class USB can be listed by using the select sub-option. See cfgadm(1M).
The following hardware-specific functions are defined:
This command requires the mandatory config value to be specified using the -o option.
Sets the USB configuration of a multi-configuration USB device at ap_id to configuration index n. The device is set to this configuration henceforth and this setting persists across reboots, hot-removes, and unconfigure/configure of the device.
Valid values of n range from 0 to (Nconfigs -1). The device is reset by a disconnect followed by a configure. The configure causes the device to be configured to the new configuration setting.
If any of these steps fail, the configuration file and the device are restored to their previous state and an error message is issued.
Performs a software reset (re-enumeration) of the device. This is the equivalent of removing the device and inserting it back again. The port on the hub is power cycled if the hub supports power cycling of individual ports.
If the connected device is a hub, this function has the effect of resetting that hub and any devices down the tree of which it is the root.
If any of these steps fail, the device is restored to its previous state and an error message is issued.

The following command lists the status of all USB devices on the system:
# cfgadm Ap_Id Type Receptacle Occupant Condition usb0/1 USB-hub connected configured ok usb0/2 unknown empty unconfigured ok usb0/1.1 USB-storage connected configured ok usb0/1.2 unknown empty unconfigured ok usb0/1.3 unknown empty unconfigured ok usb0/1.4 USB-device connected configured ok
Notice that cfgadm treats the USB-device device at ap_id usb0/1.4 as a single unit, since it cannot currently control individual interfaces.
Example 2 Listing the Status of a Port with No Device Plugged In
The following command lists the status of a port with no device plugged in:
example# cfgadm -l usb0/1.3 Ap_Id Type Receptacle Occupant Condition usb0/1.3 unknown empty unconfigured ok
Example 3 Listing the Status of the Same Port with a Device Plugged In
The following command lists the status of the same port after physically plugging in a device that configures without problems:
example# cfgadm -l usb0/1.3 Ap_Id Type Receptacle Occupant Condition usb0/1.3 USB-hub connected configured ok
Example 4 Unconfiguring an Existing USB Device
The following command unconfigures the USB device attached to usb0/1.3, then displays the status of the ap_id:
example# cfgadm -c unconfigure usb0/1.3 Unconfigure the device: /devices/pci@0,0/pci8086,7112@7,2/hub@2:2.3 This operation suspends activity on the USB device Continue (yes/no)? Enter: y example# cfgadm -l usb0/1.3 Ap_Id Type Receptacle Occupant Condition usb0/1.3 unknown connected unconfigured ok
Example 5 Unconfiguring and Logically Disconnecting an Existing USB Device
The following command unconfigures and logically disconnects a USB device attached to usb0/1.3:
example# cfgadm -c disconnect usb0/1.3 Disconnect the device: /devices/pci@0,0/pci8086,7112@7,2/hub@2:2.3 This operation suspends activity on the USB device Continue (yes/no)? Enter: y example# cfgadm -l usb0/1.3 Ap_Id Type Receptacle Occupant Condition usb0/1.3 unknown disconnected unconfigured ok
A disconnect implies that cfgadm does an unconfigure first. The receptacle status now shows disconnected, even though the device is still physically connected. In this case, a physical hotplug or using the cfgadm -c configure on the ap_id brings it back on-line.
Example 6 Configuring a Previously Unconfigured USB Device
The following command configures a USB device that was previously attached to usb0/1.3:
example # cfgadm -yc configure usb0/1.3 example# cfgadm -l usb0/1.3 Ap_Id Type Receptacle Occupant Condition usb0/1.3 unknown connected configured ok
Example 7 Resetting a USB Device
The following command resets a USB device:
example# cfgadm -x usb_reset usb0/1.3 Reset the device: /devices/pci@0,0/pci8086,7112@7,2/hub@2:2.3 This operation suspends activity on the USB device Continue (yes/no)? Enter: y
Example 8 Displaying Detailed Information About a USB Device
The following command displays detailed information about a USB device. This device shows the following USB-specific information in the 'Information' field:
Manufacturer string: Iomega
Product string: USB Zip 250
Number of configurations supported: 1
Configuration currently active: 0
Configuration string descriptor for configuration 0: Default
example# cfgadm -lv usb0/1.5 Ap_Id Receptacle Occupant Condition Information When Type Busy Phys_Id usb0/1.5 connected configured ok Mfg:"Io mega" Product:"USB Zip 250" NConfigs:1 Config:0 : Default
example# cfgadm -l -s "cols=ap_id:info" usb0/1.5 Ap_Id Information usb0/1.5 Mfg:"Iomega" Product:"USB Zip 250" NConfigs:1 Config:0 : Default
Example 9 Displaying Detailed Information About All USB Devices
The following command displays detailed information about all USB devices on the system:
example# cfgadm -l -s "select=class(usb),cols=ap_id:info" Ap_Id Information usb0/1 Mfg:<undefined> Product:<undefined> NConfigs:1 Config:0 <no cfg str descr> usb0/2 usb0/1.1 Mfg:<undefined> Product:<undefined> NConfigs:1 Config:0 <no cfg str descr> usb0/1.2 usb0/1.3 usb0/1.4 Mfg:"Wizard" Product:"Modem/ISDN" NConfigs:3 Config:1 : V.90 Analog Modem usb0/1.5 Mfg:"Iomega" Product:"USB Zip 250" NConfigs:1 Config:0 : Default usb0/1.6 Mfg:"SOLID YEAR" Product:"SOLID YEAR USB"NConfigs:1 Config:0 <no cfg str descr> usb0/1.7
Lines containing only an ap_id are empty ports. These can be filtered out. This example only lists USB ap_ids with connected devices, and information about those devices.
example# cfgadm -l -s "select=class(usb),cols=ap_id:info" | grep Mfg usb0/1 Mfg:<undefined> Product:<undefined> NConfigs:1 Config:0 <no cfg str descr> usb0/1.1 Mfg:<undefined> Product:<undefined> NConfigs:1 Config:0 <no cfg str descr> usb0/1.4 Mfg:"Wizard" Product:"Modem/ISDN" NConfigs:3 Config:1 : V.90 Analog Modem usb0/1.5 Mfg:"Iomega" Product:"USB Zip 250" NConfigs:1 Config:0 : Default usb0/1.6 Mfg:"SOLID YEAR" Product:"SOLID YEAR USB" Config:0 <no cfg str descr>
Example 10 Listing Information About a Multi-configuration USB Device
The following example lists information about a multi-configuration USB device.
Notice the NConfigs field: the configurations available for this device are 0, 1, and 2 (0 to (NConfigs-1)).
example# cfgadm -l -s "cols=ap_id:info" usb0/1.4 Ap_Id Information usb0/1.4 Mfg:"Wizard" Product:"Modem/ISDN" NConfigs:3 Config:1 V.90 Analog Modem"
Example 11 Setting the Current Configuration of a Multi-configuration USB Device
The following example sets the current configuration of a multi-configuration USB device:
example# cfgadm -o config=2 -x usb_config usb0/1.4 Setting the device: /devices/pci@1f,2000/usb@1/device@3 to USB configuration 2 This operation suspends activity on the USB device Continue (yes/no)? Enter: y USB configuration changed successfully.
The device path should be checked to ensure that the right instance of a device is being referred to, in the case where multiple devices of the exact same type are on the same bus. This information is available in the 'Information' field.
Hardware specific library for generic USB device administration

cfgadm(1M), config_admin(3CFGADM), attributes(5), scsa2usb(7D), usba(7D)
Universal Serial Bus 1.1 Specification (www.usb.org)
Oracle Solaris Administration: Common Tasks
cfgadm(1M) can not unconfigure, disconnect, reset, or change the configuration of any USB device currently opened by any application. These operations also fail on a hub if a device in its hierarchy is opened by an application. See scsa2usb(7D) for unconfiguring a USB mass-storage device that is currently in use.
Only super-users can execute any functions on an attachment point. However, one need not be a super-user to list the attachment points.
