usbprobe -- probe the USB bus for connected devices

Syntax

usbprobe [ -DdCciev ] [ -b busnum ] [ -I file ] [ -O file ] [ -a address | -p path ]
usbprobe -h

Description

The usbprobe command probes the USB bus for all connected devices. By default, it will probe all USB busses and display a single line for each device found. Each line lists the USB device path, the device number on the bus, the device type, and a device description.

Options


-D
Print debugging output as well as the default.

-d
Display device and device descriptor information.

-C
Display USBDI child instance information.

-c
Display configuration descriptor info (includes -d).

-i
Display interface descriptor information.

-e
Display endpoint descriptor information (includes -i).

-v
Verbose output (same as -e and -C ).

-I file
Use file as input instead of /dev/usbprobeXX. The file must have been produced previously using the -O option.

-O file
Write a file containing usbprobe output, suitable for using as input with the -I option.

-b busnum:
Limit output to a specific bus.

-a address
Limit output to devices with a specific address. The -a option cannot be used with the -p option.

-p path
Limit output to devices with a specific path. The path for a device is the sequence of the port numbers between the root hub and the device, separated with dots. For example, 2.5 means that the device is connected to port #5 of a hub connected to port #2 of the root hub. The path for the root hub is 0.

-h
Display command help.

Files


/dev/usbprobeXX
The /dev/usbprobeXX devices are read-only and contain information about USB devices such as host controllers, hubs, and attached USB peripherals. The XX in the device name is a number indicating which host controller is being examined. The contents of these pseudo devices are meant to be used only by the usbprobe command and may change without notice.
