How to Find USB device serial Number in VB.NET

I have found a VB code to find the serial number of an USB device at http://omnibus.uni-freiburg.de/~albers/snippets/usbinfo10.zip. I have not tried it in VB as I want to use the code in VB.NET. However converting it in VB.NET, I had to change many of things in it. Some how I managed to resolve all the complier errors. But executing the application gives runtime error. "arithmetic operation result in an overflow" at the place shown in the following extract of code. Possibly it may be overflow caused by constant value of "&HC30C" assigned to a SHORT datatype.
So, whether the "&HC30C" value is correct ?
whether VB.NET compitible code of USBINFO10 is available ?
Can experts help me to convert USBINFO10 code in to VB.NET ?
Private Structure typGUID ' 10h/16 bytes, no paddings

No VOLUME serial number needed. It gets changed by formatting the disk / usb drive.
I am concerned about Hardware/manufacturer serial number that exist in HDDs and USB drives..

Try this (converted from C# code):

you are Genius indeed. Right on target. As I got a required solution, the question tend to end. I would still desire common code to find HDD, and USB manufacturer's serial number.
