%device_name%, %device_desc%, %drive%, %serial_number%, %vid%, %pid%, %vid_hex%, %pid_hex%
, %device_type%, %service_name%, %device_class%, %device_mfg%

USBDeview will automatically replace these variables with the appropriate data of the device that you inserted.
For example, if you want to pass to your exe file 2 parameters – the serial number of the device, and the drive letter:

c:\temp\test.exe “%serial_number%” “%drive%”

Known Limitations/Issues

For all devices except ‘Mass Storage’ Devices:
If you plug a device to one USB port, and then you plug the same device to another USB port, a new
record of the same device will be created for each USB port that you plug.
So if you see multiple lines for exactly the same device, it means that you plugged it to
different USB ports. The USB ports that you plugged are specified in ‘Hub/Port’ column.

However, for ‘Mass Storage’ device, only one record is created for each device, even if you plug it to
different USB port.
When a USB device is added/removed on your local computer, USBDeview utility
automatically updates the list of USB devices.

But… If you USBDeview is connected to a remote computer, the list won’t refresh automatically when a device
is added or removed. You must refresh it manually, by pressing F5 key.

Connecting To Remote Computer

The following command-line options allows you to connect to remote computers.
You must login to the remote computer with admin user in order to use these options.

/remote <\\Computer Name>

Allows you to connect a single remote computer.

For Example:

USBDeview.exe /remote \\MyComp
/remotefile <Computers List File>

Allows you to connect multiple computers, and view all their USB activity in one window.
The computers list file should be a simple Ascii text file with computer names separated by
colon, semicolon, space, tab characters or CRLF.

For Example:

USBDeview.exe /remotefile “c:\temp\comp.txt”

In order to successfully get full admin access to the remote computer, read this Blog post:
How to connect a remote Windows 7/Vista/XP computer with NirSoft utilities.

Connecting To external SYSTEM registry file

If you have the ‘SYSTEM’ registry file of external operating system, you can use
the following command-line option to read the USB devices list from it:

/regfile <SYSTEM Registry File>

For Example:

USBDeview.exe /regfile “c:\temp\regfiles\SYSTEM”

USBDeview.exe /regfile “d:\windows\system32\config\SYSTEM”

This option has some limitations:

You cannot read a Registry file of Windows XP/2003/Vista from Windows 2000 Machine.
USBDeview works in read-only mode. (You cannot uninstall a device from external file)

Stop/Disconnect Command-Line Options

/stop {/showmsg} {\\RemoteComputer} <Device Name>

Stop/disconnect a USB device by specifying its name or description.
You don’t have to specify the whole name or description.
You can also specify only a part of the name or description string, and USBDeview
will identify it. For example, If the device name is ‘Kingston DataTraveler 2.0’, you can
simply put ‘kingston’ or ‘DataTraveler’ in the device name parameter, and USBDeview will disconnect the
right device.
You can also specify the instance ID string of the device.

If you want that a message/balloon will be displayed after the device is disconnected,
add the ‘/showmsg’ parameter. (Windows 2000 displays a message-box, Windows XP displays a balloon)

If you want to disconnect a device in a remote computer, specify the remote computer name,
with \\ prefix. You must login to the remote computer with admin rights in order to do that.

Examples:

USBDeview.exe /stop /showmsg “DVD RW”

USBDeview.exe /stop “DataTraveler”

USBDeview.exe /stop \\comp01 “SanDisk Cruzer”

USBDeview.exe /stop “USB\Vid_1058&Pid_1023\8539583490834690”
/stop_by_serial {/showmsg} {\\RemoteComputer} <Device Serial>

Similar to /stop command, but instead of specifying a device name, you should specify the
serial number of the device. Works only with mass storage devices.

Examples:

USBDeview.exe /stop_by_serial ea051261

USBDeview.exe /stop_by_serial /showmsg 876534513
/stop_by_drive {/showmsg} {\\RemoteComputer} <Drive Letter>

Stop/disconnect a USB device by specifying its drive letter.
Works only with USB flash drives and CD/DVD devices.

Examples:

USBDeview.exe /stop_by_drive g:

USBDeview.exe /stop_by_drive /showmsg f:

USBDeview.exe /stop_by_drive /showmsg \\comp02 t:
/stop_by_class {/showmsg} {\\RemoteComputer} <USB Class;USB SubClass;USB Protocol>

Stop/disconnect a USB device by specifying the class/subclass/protocol combination.

For example, if you want to stop all ‘Mass Storage’ devices,
you should specify the following class/subclass/protocol combination: 08;06;50

Examples:

USBDeview.exe /stop_by_class /showmsg 08;06;50

USBDeview.exe /stop_by_class 03;01;02
/stop_by_pid {/showmsg} {\\RemoteComputer} <VendorID;ProductID>

Stop/disconnect a USB device by specifying the VendorID/ProductID. You can specify only the VendorID if you want to disconnect all devices with that VendorID.

Examples:

USBDeview.exe /stop_by_pid /showmsg 13fe;1a00

USBDeview.exe /stop_by_pid 04f9
/stop_all {/showmsg} {\\RemoteComputer}

Stop/disconnect all USB devices currently connected to your computer.

Disable/Enable/Remove Command-Line Options

Starting from version 1.20, you can also use the following commands to disable, enable or remove
USB devices from command-line:

/disable {\\RemoteComputer} <Device Name>
/disable_by_serial {\\RemoteComputer} <Device Serial>
/disable_by_drive {\\RemoteComputer} <Drive Letter>
/disable_by_class {\\RemoteComputer} <USB Class;USB SubClass;USB Protocol>
/disable_by_pid {\\RemoteComputer} <VendorID;ProductID>
/disable_all {\\RemoteComputer}
/enable {\\RemoteComputer} <Device Name>
/enable_by_serial {\\RemoteComputer} <Device Serial>
/enable_by_drive {\\RemoteComputer} <Drive Letter>
/enable_by_class {\\RemoteComputer} <USB Class;USB SubClass;USB Protocol>
/enable_by_pid {\\RemoteComputer} <VendorID;ProductID>
/enable_all {\\RemoteComputer}
/disable_enable {\\RemoteComputer} <Device Name>
/disable_enable_by_serial {\\RemoteComputer} <Device Serial>
/disable_enable_by_drive {\\RemoteComputer} <Drive Letter>
/disable_enable_by_class {\\RemoteComputer} <USB Class;USB SubClass;USB Protocol>
/disable_enable_by_pid {\\RemoteComputer} <VendorID;ProductID>
/disable_enable_all {\\RemoteComputer}
/remove {\\RemoteComputer} <Device Name>
/remove_by_serial {\\RemoteComputer} <Device Serial>
/remove_by_drive {\\RemoteComputer} <Drive Letter>
/remove_by_class {\\RemoteComputer} <USB Class;USB SubClass;USB Protocol>
/remove_by_pid {\\RemoteComputer} <VendorID;ProductID>
/remove_all {\\RemoteComputer}
/remove_all_connected

– Remove all connected USB devices.
/remove_all_disconnected

– Remove all disconnected USB devices.

Disable, enable and remove actions require elevation (‘Run As Administrator’).
You can use the above command-line options with elevation by adding /RunAsAdmin to the command, for example:

USBDeview.exe /RunAsAdmin /disable “USB\Vid_1058&Pid_1023\8539583490834690”

Check if a device is connected/disconnected or enabled/disabled

Starting from version 2.70, you can check whether a device is connected/disconnected or enabled/disabled by using
the following command-line options:

/is_connected {\\RemoteComputer} <Device Name>
/is_connected_by_serial {\\RemoteComputer} <Device Serial>
/is_connected_by_drive {\\RemoteComputer} <Drive Letter>
/is_connected_by_class {\\RemoteComputer} <USB Class;USB SubClass;USB Protocol>
/is_connected_by_pid {\\RemoteComputer} <VendorID;ProductID>
/is_disabled {\\RemoteComputer} <Device Name>
/is_disabled_by_serial {\\RemoteComputer} <Device Serial>
/is_disabled_by_drive {\\RemoteComputer} <Drive Letter>
/is_disabled_by_class {\\RemoteComputer} <USB Class;USB SubClass;USB Protocol>
/is_disabled_by_pid {\\RemoteComputer} <VendorID;ProductID>

When using the above commands, USBDeview returns the number of disabled or connected devices that match the specified string.

For example, the following batch file will display 1 if the device with serial number 7538957348957398 is connected or 0 if the device is not connected:

USBDeview.exe /is_connected_by_serial “7538957348957398”

echo %ERRORLEVEL%
