How to get the serial number, model,... of the usb key connected on to pc?

Something like this:

C#

ManagementObjectSearcher USB = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
          ManagementObjectCollection USBinfo = USB.Get();
          string info = "";
          foreach (ManagementObject MO in USBinfo)
          {
              info = (string)MO["SerialNumber"];
          }

But this gives me the serial number for disk, not usb key.

Also tried this:

ManagementObjectSearcher MOS = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
ManagementObjectCollection model = MOS.Get();
string mark = "";

foreach (ManagementObject obj in model)
{
if (obj["Name"].ToString() == ("\\\\.\\PHYSICALDRIVE") & obj["InterfaceType"].ToString() == "USB")
{
mark = (string)(obj["PNPDeviceID"].ToString());

}

}

textBox7.Text = "ID is: " + mark.ToString();

and i don't get anything.

Hello

try changing this code ::
"if (obj["Name"].ToString() == ("\\\\.\\PHYSICALDRIVE") & obj["InterfaceType"].ToString() == "USB")"
to this one ::
"if (obj["Name"].ToString().Contains(("\\\\.\\PHYSICALDRIVE")) & obj["InterfaceType"].ToString() == "USB")"

this must show the exact usb serial number !

and also the casting method here -> "mark = (string)(obj["PNPDeviceID"].ToString());" is redundant ! you may better remove that cast (string).

Try querying for the WMI class Win32_LogicalDisk, it has one property called VolumeSerialNumber. Other properties like DriveType and MediaType will help you identifying the type or drive. With the property PNPDeviceID it could be possible to track it down to the physical USB device information.
There's a long disccussion here http://social.technet.microsoft.com/Forums/windowsserver/en-US/09c9814a-38fa-4b16-bc8f-01329882a791/powershell-wmi-get-usb-storage-devices-only[^] with hints that could help.
