Try using Win32_DiskDrive instead. I'm not 100% sure (read: I'm 
about 1% sure) what constitutes the USB serial number. The only
thing I'm fairly sure about is that it's *not* the volume label.

The PNPDeviceID looks good, even if it might need a bit of parsing:

<code>
import wmi

c = wmi.WMI ()
for usb in c.Win32_DiskDrive (InterfaceType="USB"):
  print usb.PNPDeviceID

</code>
