This is not really a Cocoa question, but I'll point you in the right direction.

If the device is mounted as a drive and you know the path under which the device is mounted you can use the statfs() system call to get the filing system path of the underlying device, which you can then open as a simple file.

If you don't know the path under which your USB drive is mounted but the user us capable of picking it from a list you can get the list of mounted removable media from:
[[NSWorkspace sharedWorkspace] mountedRemovableMedia]
To make this list look pretty you might want to strip the "/Volumes/" of the front of each item before you display them.

If you don't know where the device is mounted, or if it has some unsupported file system format so it is never going to be mounted, then you are going to need to dig deeper into the world of IOKit, which is definitely off topic for this list. I'd start by reading the documentation at on IOKit and the USB system at:
http://developer.apple.com/documentation/DeviceDrivers/ Conceptual/IOKitFundamentals/
http://developer.apple.com/documentation/DeviceDrivers/ Conceptual/USBBook/
and then move on to the Apple USB list for more help.

    Cheers,
        Nicko
