我需要让我的程序仅与某一制造商的USB闪存驱动器配合使用，并忽略所有其他制造商的USB闪存驱动器。
在使用.NET 2.0时，是否可以检查Windows上是否插入了特定的USB卡？如何实现？
如果我通过WMI找到它，是否可以确定USB驱动器所在的驱动器号？

编辑： 添加了打印驱动器字母的代码。
检查一下这个示例是否适合你。它使用 WMI。
Console.WriteLine("Manufacturer: {0}", queryObj["Manufacturer"]);
...
Console.WriteLine(" Name: {0}", c["Name"]); // here it will print drive letter
完整的代码示例：
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();
}
}
}
我认为这些属性应该能够帮助你区分真正的USB驱动器和其他驱动器。测试几个U盘以检查数值是否相同。这里有完整的Win32_DiskDrive属性参考：

你可以使用未管理的Win32 API调用来处理此问题。

通过Win32 CM_（设备管理）或WMI获取PNP ID。查找VID（供应商ID）。
我在Win32_USBControllerDevice和Win32_DiskDrive下看到刚插入的设备的信息。

您可以通过WMI获取此信息。以下是一个vbs脚本（复制到文本文件中并添加.vbs后缀以运行），它使用WMI获取有关Win32_DiskDrive对象的一些信息。 制造商信息可能只是标准磁盘驱动器，但型号号码可能包含您要查找的内容。
Set Drives = GetObject("winmgmts:{impersonationLevel=impersonate,(Backup)}").ExecQuery("select * from Win32_DiskDrive")
for each drive in drives
Wscript.echo "Drive Information:" & vbnewline & _

如果
Win32_DiskDrive 对象无法提供您所需的信息，您还可以查看 WMI 对象的 Win32_PhysicalMedia 类。它们具有制造商、型号、零件编号和描述属性，可能会证明有用。- Curtis

以防其他人也像我一样疯狂地使用C++-CLI，这里是smink答案的一个移植版本：
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();
}
注意：我必须在项目属性中手动添加对
System.Management 库的引用。- Jon Cage

嗨，尝试使用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
模型可能比制造商更有帮助。 如果您现在想将应用程序锁定为一个制造商和一个（些）固件版本，则查看 FirmwareRevision。
希望对您有所帮助。
