I can't help with the issue, I'm afraid, but I can shed a little light 
on this.

The phone contains an image of its "Driver CD" and presents this to the 
USB host as a CD-ROM, as well as presenting itself as a mass storage device.

The idea is that you can just plug the phone into your PC, it sees a CD 
drive with the drivers disc in and installs them (and, optionally, any 
additional software). Then it sees the device properly. This is usually 
for Windows users.
