CD Drive letter - This is different to the normal question

[Tel2]

I've got a project that uses an OCX for writing to CD.
It accesses the CD via Adapter, ID And LUN, (Using ASPI)
I get useful information like the Product Ident, etc... but NOT Assigned Drive letter.

I also use another useful OCX for figuring out when a CD has been inserted.
This OCX reports back just a drive letter.

Is there any call I can make to get a CD ROM's assigned Drive letter and product Ident? (As in device manager lists the assigned drive letter etc...)

This way I could know for fact that the CD ROM Drive that reports a CD has been inserted is infact the CD Writer.

OK More information.

From the CD Notify OCX (For insertation of a CD) I just get a drive letter, Lets say H

From the CD Writing OCX I get
Adapter 0 ID = 1 Lun = 0 Name = HP CD-Writer+ 8200a1.0g ProductIdent : CD-Writer+ 8200a1.0g ProductRevision : 1.0g Typ : 5

Is there any way I can find out H Drive is a CD-Writer+ 8200a

Under Device Manager (Win 9x/ME) you can see the drive letter for the device CD-Writer+ 8200a is H.
(Mind you I'm hoping this will still work under win2k, I'm using WinME myself.)

1) Is it just reading the Registry to asertain that or is it an API Call?
2) Is there any API Calls I can use to get the product Ident from a drive letter?
3) Can I get the Drive letter from an adapter number, ID, Lun?

I spose are my real questions.

Thanks
