Answer 2

Just in case anyone else is crazy enough to do this in C++-CLI, here's a port of smink's 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 reference to the System.Management library in my porject properties.
