Walkman not logical drive?

[oex]

Hey guys,

I plug my walkman in to USB but it has no drive letter after it's name in My Computer and does not list with GetLogicalDrives function any ideas why?

I have tested with a normal USB stick which comes up fine

EDIT: On further examination when I get the 'What do you want to do' window on device insertion I notice the MP3 player is a 'portable device' vs 'removable disk' for my USB stick....

I once had a similar problem with a camera. Finally I found out in some obscure setting level that the camera could alternatively behave as device or drive when communicating with the computer.

I have been looking for obsure settings and am inundated :lol.... you dont remember which one? :bg.... This is definately the problem.... It is a device that charges and has storage space of 2Gb....

Accessing the device in explorer is through a path like My Computer\WALKMAN NWZ-B135
and the storage space through a path like My Computer\WALKMAN NWZ-B135 \Storage Media

It doesnt fire a DBT_DEVICEARRIVAL message (though it does fire a DBT_DEVNODES_CHANGED message and I'm not sure whether this means I should be calling this:
