Description

USBDeview is a small utility that lists all USB devices that currently connected to your computer, as well as all USB devices that you previously used. 

For each USB device, extended information is displayed: Device name/description, device type, serial number (for mass storage devices), the date/time that device was added, VendorID, ProductID, and more... 
USBDeview also allows you to uninstall USB devices that you previously used, disconnect USB devices that are currently connected to your computer, as well as to disable and enable USB devices. 
You can also use USBDeview on a remote computer, as long as you login to that computer with admin user.

Using USBDeview

USBDeview doesn't require any installation process or additional DLL files. Just copy the executable file (USBDeview.exe) to any folder you like, and run it. 

The main window of USBDeview displays all USB devices installed on your system. You can select one or more items, and then disconnect (unplug) them , uninstall them, or just save the information into text/xml/html file.

USBDeview Columns Description

• Device Name: Specifies the device name. For some device, this column may display meaningless name, like "USB Device". If the device name is meaningless, try to look at the Description column.
• Device Description: The description of the device.
• Device Type: The device type, according to USB class code. For more information about USB classes: USB Class Codes.
• Connected: Specifies whether the device is currently connected to your computer. If the device is connected, you can use the 'Disconnect Selected Devices' option (F9) to disconnect the device.
• Safe To Unplug: Specifies whether it's safe to unplug the device from the USB plug without disconnecting it first. If the value of this column is false, and you want to unplug this device, you must first disconnect this device by using the 'Disconnect Selected Devices' option (F9) of USBDeview utility, or by using the 'Unplug or Eject Hardware' utility of Windows operating system.
• Drive Letter: Specifies the drive letter of the USB device. This column is only relevant to USB flash memory devices and to USB CD/DVD drives. Be aware that USBDeview cannot detect drive letters of USB hard-disks.
• Serial Number: Specifies the serial number of the device. This column is only relevant to mass storage devices (flash memory devices, CD/DVD drives, and USB hard-disks).
• Created Date: Specifies the date/time that the device was installed. In most cases, this date/time value represents the time that you first plugged the device to the USB port. However, be aware that in some circumstances this value may be wrong. Also, On Windows 7, this value is initialized with the current date/time on every reboot.
• Last Plug/Unplug Date: Specifies the last time that you plugged/unplugged the device. This date value is lost when you restart the computer.
• VendorID/ProductID: Specifies the VendorID and ProductID of the device. For unofficial list of VendorID/ProductID, click here.
• USB Class/Subclass/Protocol: Specifies the Class/Subclass/Protocol of the device according to USB specifications. For more information about USB classes: USB Class Codes.
• Hub/Port: Specifies the hub number and port number that the device was plugged into. This value is empty for mass storage devices.

Notice: According to user reports, On some systems the 'Last Plug/Unplug Date' and the 'Created Date' values are initialized after reboot. This means that these columns may display the reboot time instead of the correct date/time.

'Vendor Name' And 'Product Name' Columns

Starting from version 1.35, you can view the vendor name and product name of your USB devices. In order to use this feature, you have to download the USB ID's list of Stephen J. Gowdy (http://www.linux-usb.org/usb.ids) and put the file in the same folder of USBDeview.exe 

The name of the file must remain as 'usb.ids'.

Speed Test for USB Flash Drives

Starting from version 1.40, USBDeview allows you to test the read/write speed of your USB flash drive. The test is made by writing a large file (named $speed_test_nirsoft$.dat) into your USB flash drive, and then reading it back for testing the read speed. Be aware that you need at least 100 MB of free disk space in order to successfully make this speed test. Also, be aware that this test is made with sequential read and write operations. When using multiple small files, the read/write performances are usually much lower than sequential read/write.

In order to make a speed test to your flash drive, simply select the desired item in the main window, and then choose the 'Speed Test' option from the File menu, or press Ctrl+T. In the speed test window, verify that the selected drive letter is the right one, and then press the 'Start Test' button. Wait a few seconds until the write and read tests are finished.

Publishing Your Speed Test Result

If you want to share your speed test results, so other people that want to purchase a USB flash drive will be able to easily compare the speed of different flash drives, you can use the 'Publish Test Result' option to do that.

When you successfully finish a speed test, the 'Publish Test Result' button is automatically enabled. Clicking this button opens a new window that displays all the data that will be sent to http://usbspeed.nirsoft.net Web site, and ask you the confirm the speed test publishing. Be aware that only the data displayed in this window is transmitted to http://usbspeed.nirsoft.net Web site. USBDeview doesn't send the serial number of your USB device or any other information that may violate your privacy.

AutoPlay

Starting from version 1.10, USBDeview allows you to automatically run a file on USB flash memory devices, according to AutoRun.inf filename. You can manually activate the AutoPlay feature by selecting the desired device and pressing F8. Alternatively, You can check the "AutoPlay When Device Is Connected" option, and then the AutoPlay feature will be automatically activated when you insert a USB flash memory device. 

Be aware that this feature only works if USBDeview detects the drive letter of the device.

Execute a command when you insert a USB device

Starting from version 1.10, USBDeview allows you to execute a command from exe/cmd/bat file in every time that insert a USB device to your system. In order to use this feature, go to 'Options->Advanced Options', select the 'Execute..' check-box, and type the exe/cmd file that you want to run. You can also use the following special variables in this command string: %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, UDBDeview utility automatically updates the list of USB devices.
  But... If you UDBDeview 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 

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"
