external usb drive detected as fixed, get bustype ?

[par]

Hello there,

when using usb flashdrive or usb harddisks, drive.gettype gets "drive_removable" when it is a flashdrive, and "drive_fixed" when it is a usb harddisk. In Windows this is expected behaviour. Is it at all possible to get the bustype (usb, sata, scsi, etc. ) with some lua code ?

My goal is, that when a usb harddrive is connected, i can treat this drive as "drive_removable"

with kind regards and thanx in advance
