Thanks to everyone's suggestions I finally got the
IOCTL_STORAGE_QUERY_PROPERTY-call working. However, the results are a
bit disappointing. As mentioned earlier my goal was to determine the
EXACT bus type.

Initially the STORAGE_BUS_TYPE enumerator returned by
IOCTL_STORAGE_QUERY_PROPERTY looked very promising (i.e. it offers a
large variety of bus types)  :
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/storage/hh/storage/structs-general_0266117e-e310-4db5-82c5-568b178c03fc.xml.asp
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/storage/hh/storage/structs-general_196c7640-0a2d-4567-8958-1244c46b84a6.xml.asp
typedef enum _STORAGE_BUS_TYPE {
  BusTypeUnknown = 0x00,
  BusTypeScsi,
  BusTypeAtapi,
  BusTypeAta,
  BusType1394,
  BusTypeSsa,
  BusTypeFibre,
  BusTypeUsb,
  BusTypeRAID,
  BusTypeiSCSI,
  BusTypeSATA,
  BusTypeSAS,
  BusTypeMaxReserved = 0x7F
} STORAGE_BUS_TYPE, *PSTORAGE_BUS_TYPE;

However, when I execute the code it still isn't e.g. able to
distinguish between SATA and ATA. I wasn't yet able to test it on a
SATA removable storage device but instead I tried it with a hard disc
(I will try a SATA removable storage device later on today, as I
currently don't have one available, but I have no reason to expect the
behaviour will be different).

Anyway, instead of enumerating the GUID_DEVINTERFACE_CDROM devices I
enumerated the GUID_DEVINTERFACE_DISK in order to get hard discs.

For my SATA hard disc I get this :

DEVICE01::DevicePath  =
\\?\ide#diskwdc_wd1600jd-22hbb0_____________________08.02d08#4457572d414d384c333138393733_030_0_0_0_0#{53f56307-b6bf-11d0-94f2-00a0c91efb8b}
DEVICE01::SptiHandle  = 0x00A4
DEVICE01::BusType     = ATA (STORAGE_BUS_TYPE=3)

So basically this IOCTL_STORAGE_QUERY_PROPERTY is unable to recognize
SATA and simply reports ATA. Which isn't wrong but it also isn't
detailled enough especially if you consider that a BusTypeSATA does
exist in the enum.

In fact, it has the same accuracy as the method I initially employed.
This method consisted out of interpreting the device path :
DevicePath=\\?\ide#......=> ATA
DevicePath=\\?\spb2#.....=> IEEE
DevicePath=\\?\usbstor#..=> USB
DevicePath=\\?\scsi#.....=> SCSI

I welcome anyone who has any ideas on how to really benefit from the
wealth of bus types that STORAGE_BUS_TYPE has to offer. 

Thank you,
