How to show usb Device Name?

How to know the usb device name?
How to create usb mass storage device??
and how to put command data to the device??
OS is \"windows xp\"
because , this os had the base device driver (usbstor.sys)
when you plug in the usb storage device , it\'ll start.
but how to show the device name??

I have a pen driver for usb, that\'s a small storage disk
when you put it on your pc, it\'ll auto run with
                                      \"usbstor.sys\" driver,
I can follow the usbview source code to find and create ROOT HUB name , and find the pen driver vendor ID and product ID
but I don\'t know how to open it or create it
is create device need device name?? doesn\'t it
I need to through some control data to the deivce
Like the device define \"low lever formate\" command

Your questions are so strange:
1. what do you mean the device name? where did you see it?
2. what\'s the meaning of \'create usb mass storage device\'? manufacture a hardware device? or, just create a fdo in your driver?
3. what command and waht device do you want to do with?
