DESCRIPTION

The options are as follows:

-u unit

Limit device range to USB devices connected to the given USBUS unit.

-a addr

Limit device range to the given USB device index. Should only be used in conjunction with the unit argument.

-d [ugen]<unit>.<addr>

Limit device range to USB devices connected to the given unit and address. The unit and address coordinates may be prefixed by the lowercased word "ugen".

-h

Show help and available commands.

The following commands may be used with usbconfig:

set_config cfg_index

Choose the configuration for the USB device. Valid values range from zero to the number reported as the bNumConfigurations in dump_device_desc output. The special value of 255 unconfigures the device, detaching the interface drivers and reducing the power consumption to minimum, but without going into power saving mode or detaching from the bus. In some cases, it prevents the device from charging.

set_alt alt_index

Choose the alternate interface for the USB device. Alternative settings for the current configuration are available as the bAlternateSetting in dump_curr_config_desc output. Usually there is no need to adjust this setting.

set_template template

Set the global USB device side template. See usb_template(4) for more information.

get_template

Get the current USB device side template.

add_dev_quirk_vplh vid pid lo_rev hi_rev quirk_name

Add a quirk by specifying the Vendor ID, Product ID, low and high revision numbers, and the quirk name. See usb_quirk(4) for more information.

remove_dev_quirk_vplh vid pid lo_rev hi_rev quirk_name

Remove a quirk.

add_quirk quirk_name

Add quirk for the currently selected USB device.

remove_quirk quirk_name

Remove a quirk for the currently selected USB device.

dump_all_desc

Display the device and configuration descriptors.

dump_quirk_names

Display the list of supported quirk names.

dump_device_quirks

Display the list of current device quirks.

dump_device_desc

Display the device descriptor.

dump_curr_config_desc

Display current configuration descriptor.

dump_all_config_desc

Display all the configuration descriptors.

dump_string index

Display string descriptor at selected index.

dump_info

Display summary information about the device.

show_ifdrv

Display the list of interface drivers (such as ukbd(4) or u3g(4)) currently attached to the device.

Force the device to suspend.

resume

Force the device to resume.

power_off

power_save

Turn the automatic suspend and resume on. This is the default for USB hubs.

do_request bmReqTyp bReq wVal wIdx wLen data...

Perform a synchronous control request on the specified device. See libusb20_dev_request_sync(3) for more information.
