How to identify the manufacturer of USB flash drives?

Question

I need my program to work only with some USB flash drives (from one manufacturer) and ignore all other USB flash drives (from other manufacturers).

Is it possible to verify that a specific USB stick is inserted in Windows using .NET 2.0? as?

If I find it through WMI, can I somehow determine which drive letter the USB drive is on?

Answer 1

EDIT: Added code to print a drive letter.

Check if this example works for you. It uses WMI.

Console.WriteLine("Manufacturer: {0}", queryObj["Manufacturer"]); ... Console.WriteLine(" Name: {0}", c["Name"]); // here it will print drive letter 

Full sample code:

 namespace WMISample { using System; using System.Management; public class MyWMIQuery { public static void Main() { try { ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_DiskDrive"); foreach (ManagementObject queryObj in searcher.Get()) { Console.WriteLine("DeviceID: {0}", queryObj["DeviceID"]); Console.WriteLine("PNPDeviceID: {0}", queryObj["PNPDeviceID"]); Console.WriteLine("Manufacturer: {0}", queryObj["Manufacturer"]); Console.WriteLine("Model: {0}", queryObj["Model"]); foreach (ManagementObject b in queryObj.GetRelated("Win32_DiskPartition")) { Console.WriteLine(" Name: {0}", b["Name"]); foreach (ManagementBaseObject c in b.GetRelated("Win32_LogicalDisk")) { Console.WriteLine(" Name: {0}", c["Name"]); // here it will print drive letter } } // ... Console.WriteLine("--------------------------------------------"); } } catch (ManagementException e) { Console.WriteLine(e.StackTrace); } Console.ReadLine(); } } } 

I think these features should help you distinguish original USB drives from others. Test a few knobs to see if the values ​​match. See the full link for Win32_DiskDrive properties here:

Answer 2

You can use unmanaged Win32 API calls to handle this.

Answer 3

Go through Win32 CM_ (Device Management) or WMI and capture the PNP identifier. Look for the VID (vendor identifier).

I see information for the device that I just inserted under Win32_USBControllerDevice and Win32_DiskDrive .

Answer 4

You can get this information through WMI. The following is a vbs script (copy to text file with .vbs to run) that uses WMI to get some information about Win32_DiskDrive objects. Manufacturer information may simply say “Standard Disc,” but the model number may have what you are looking for.

 Set Drives = GetObject("winmgmts:{impersonationLevel=impersonate,(Backup)}").ExecQuery("select * from Win32_DiskDrive") for each drive in drives Wscript.echo "Drive Information:" & vbnewline & _ "Availability: " & drive.Availability & vbnewline & _ "BytesPerSector: " & drive.BytesPerSector & vbnewline & _ "Caption: " & drive.Caption & vbnewline & _ "CompressionMethod: " & drive.CompressionMethod & vbnewline & _ "ConfigManagerErrorCode: " & drive.ConfigManagerErrorCode & vbnewline & _ "ConfigManagerUserConfig: " & drive.ConfigManagerUserConfig & vbnewline & _ "CreationClassName: " & drive.CreationClassName & vbnewline & _ "DefaultBlockSize: " & drive.DefaultBlockSize & vbnewline & _ "Description: " & drive.Description & vbnewline & _ "DeviceID: " & drive.DeviceID & vbnewline & _ "ErrorCleared: " & drive.ErrorCleared & vbnewline & _ "ErrorDescription: " & drive.ErrorDescription & vbnewline & _ "ErrorMethodology: " & drive.ErrorMethodology & vbnewline & _ "Index: " & drive.Index & vbnewline & _ "InterfaceType: " & drive.InterfaceType & vbnewline & _ "LastErrorCode: " & drive.LastErrorCode & vbnewline & _ "Manufacturer: " & drive.Manufacturer & vbnewline & _ "MaxBlockSize: " & drive.MaxBlockSize & vbnewline & _ "MaxMediaSize: " & drive.MaxMediaSize & vbnewline & _ "MediaLoaded: " & drive.MediaLoaded & vbnewline & _ "MediaType: " & drive.MediaType & vbnewline & _ "MinBlockSize: " & drive.MinBlockSize & vbnewline & _ "Model: " & drive.Model & vbnewline & _ "Name: " & drive.Name & vbnewline & _ "NeedsCleaning: " & drive.NeedsCleaning & vbnewline & _ "NumberOfMediaSupported: " & drive.NumberOfMediaSupported & vbnewline & _ "Partitions: " & drive.Partitions & vbnewline & _ "PNPDeviceID: " & drive.PNPDeviceID & vbnewline & _ "PowerManagementSupported: " & drive.PowerManagementSupported & vbnewline & _ "SCSIBus: " & drive.SCSIBus & vbnewline & _ "SCSILogicalUnit: " & drive.SCSILogicalUnit & vbnewline & _ "SCSIPort: " & drive.SCSIPort & vbnewline & _ "SCSITargetId: " & drive.SCSITargetId & vbnewline & _ "SectorsPerTrack: " & drive.SectorsPerTrack & vbnewline & _ "Signature: " & drive.Signature & vbnewline & _ "Size: " & drive.Size & vbnewline & _ "Status: " & drive.Status & vbnewline & _ "StatusInfo: " & drive.StatusInfo & vbnewline & _ "SystemCreationClassName: " & drive.SystemCreationClassName & vbnewline & _ "SystemName: " & drive.SystemName & vbnewline & _ "TotalCylinders: " & drive.TotalCylinders & vbnewline & _ "TotalHeads: " & drive.TotalHeads & vbnewline & _ "TotalSectors: " & drive.TotalSectors & vbnewline & _ "TotalTracks: " & drive.TotalTracks & vbnewline & _ "TracksPerCylinder: " & drive.TracksPerCylinder & vbnewline next 

Answer 5

If the Win32_DiskDrive objects Win32_DiskDrive not provide the information you are looking for, you can also look at the Win32_PhysicalMedia WMI object class. They have Manufacturer, Model, PartNumber, and description properties that you might find useful.

Maybe #usblib:

Answer 7

Hi try this using WMI

 Option Explicit Dim objWMIService, objItem, colItems, strComputer ' On Error Resume Next strComputer = "." Set objWMIService = GetObject("winmgmts:\\" _ & strComputer & "\root\cimv2") Set colItems = objWMIService.ExecQuery(_ "Select Manufacturer from Win32_DiskDrive") For Each objItem in colItems Wscript.Echo "Computer: " & objItem.SystemName & VbCr & _ "Manufacturer: " & objItem.Manufacturer & VbCr & _ "Model: " & objItem.Model Next 

A model may be more useful than a Manufacturer. You are viewing FirmwareRevision if you want to block your application for only one manufacturer and one (some) firmware.

Hope this helps.

Just in case, if someone else is crazy enough to do this in C ++ - CLI, here is the smink port answer:

 using namespace System; using namespace System::Management; void GetUSBDeviceList() { try { ManagementObjectSearcher^ searcher = gcnew ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_DiskDrive"); for each (ManagementObject^ queryObj in searcher->Get()) { Console::WriteLine("DeviceID: {0}", queryObj["DeviceID"]); Console::WriteLine("PNPDeviceID: {0}", queryObj["PNPDeviceID"]); Console::WriteLine("Manufacturer: {0}", queryObj["Manufacturer"]); Console::WriteLine("Model: {0}", queryObj["Model"]); for each (ManagementObject^ b in queryObj->GetRelated("Win32_DiskPartition")) { Console::WriteLine(" Name: {0}", b["Name"]); for each (ManagementBaseObject^ c in b->GetRelated("Win32_LogicalDisk")) { Console::WriteLine(" Name: {0}", c["Name"]); // here it will print drive letter } } // ... Console::WriteLine("--------------------------------------------"); } } catch (ManagementException^ e) { Console::WriteLine(e->StackTrace); } Console::ReadLine(); } 

Note. I had to manually add a link to the System.Management library in the properties of my object.
