Uniquely identifying a pendrive

Question

I am working on USB devices and can identify a usb device. But I have a theoretical question.Is it shows any usb device like portable cd drive or specifically flash drives? I could nt check all possibilities due to lack of these hardwares :). Is there any method to identify if it is a flash drive or another usb device.

Please don't beat with what you have tried. I googled regarding same but because of my least experience I couldn't find any.

Thanks

Please use the class USBSerialNumber

USBSerialNumber usb = new USBSerialNumber();
string serial = usb.getSerialNumberFromDriveLetter("f:\");
MessageBox.Show(serial);

Each pendrive has serial number which is unique.

You can use this class for this purpose.

I hope Every usb device(bth device,mouse, etc) has a serial number. Is it wrong? – Zigma Apr 09 '13 at 05:00
Yeah , each usb device has it. so pendrive also. – Freelancer Apr 09 '13 at 05:01
so will this identify a generic pen drive? in this case we need to know the usb device serial number right? – Zigma Apr 09 '13 at 05:18
serial number is written in each pendrive. and no need to know it in this case. – Freelancer Apr 09 '13 at 05:20
