Help with USB driver

Hi

I am a C/C++ programmer and am trying to do windows driver development for
the first time
What I am trying to achieve is the following..
I have a USB mass storage device with two partions on it (one read
only and other read-write).. I want to write a C++ (or C) utility that
can run in user mode and provide me the following information

The drive letters assigned to the two partitions of the USB
Some sort of functionality to change the read-only partition to read-
write and vice versa. ( Not sure if it is do-able in user-mode..)

PS: I want this to work on windows xp sp2 and up..

Any help with this would be greatly appreciated

thanks

A lot of information on this can be found here:

For this, you need a configuration utility from the device manufacturer.

Hi Pavel
thanks a lot for your reply..
I am still looking for specific windows API's or example code that can
identify the various partitions on the USB and the disk letters associated
with each partition
Also I dont want to use the vendor configuration utility and use only
windows APIs to change the read-only partition to be read-writable.. I want
this functionality to be independent of the vendor. The usb i have is a
general purpose mass storage device..

thanks
