Is there a way to determine a particular drive's InterfaceType (USB,IDE or SCSI)? Using Win32::API, I can call GetDriveType to tell if it is a fixed drive, cd-rom drive, etc but I need a way to determine whether the drive is USB, IDE, or SCSI. Any ideas?

UPDATE: Taking the excellent comments made, I have been able to come up with the following but when I run it, it accesses the floppy drive every time... I will still need to work on figuring out how to exclude the floppy drive seek unless specifically requested.

use strict;
use warnings;
use Win32::OLE qw(in);

my $objWMIService = Win32::OLE->GetObject("winmgmts:{impersonationLeve
+l=impersonate,(security)}//.");
die "Error" unless $objWMIService;
my $wmiDiskDrives = $objWMIService->ExecQuery("SELECT Caption, DeviceI
+D, InterfaceType FROM Win32_DiskDrive");

print "Device Caption  ->  InterfaceType  ->   Drive Letter\n";
print "=" x 60 . "\n";

foreach my $wmiDiskDrive ( in( $wmiDiskDrives ) ) {
    my $deviceID=$wmiDiskDrive->{DeviceId};
    $deviceID=~s/\\/\\\\/sg;
    my $map=qq|ASSOCIATORS OF {Win32_DiskDrive.DeviceID="$deviceID"} W
+HERE AssocClass = Win32_DiskDriveToDiskPartition|;
    #print "$map\n";
    my $wmipartitions = $objWMIService->ExecQuery($map);
    foreach my $wmipartition ( in( $wmipartitions ) ) {
        my $deviceID=$wmipartition->{DeviceId};
        my $map=qq|ASSOCIATORS OF {Win32_DiskPartition.DeviceID="$devi
+ceID"} WHERE AssocClass = Win32_LogicalDiskToPartition|;
        #print "\t$map\n";
        my $wmiLogicalDisks = $objWMIService->ExecQuery($map);
        foreach my $wmiLogicalDisk ( in( $wmiLogicalDisks ) ) {
            my $drive=$wmiLogicalDisk->{DeviceId};
               print join("  ->  ", $wmiDiskDrive->{Caption}, $wmiDisk
+Drive->{InterfaceType} , $wmiLogicalDisk->{DeviceId});
              print  "\n";
            }
        }
    }
