Drive Letters by Drive Type
The following drive types are defined in USBDLM:
FLOPPY Floppy drives
REMOVABLE non floppy drives with removable media as USB flash drives and card readers
FIXED Hard drives
CDROM CD / DVD / Blu-ray drives
UNKNOWN unknown, some card readers in notebooks
RAMDISK RAM drives (many RAM drives appear as FIXED, check with UsbDriveInfo)
ANY / ALL all types (use it carefully!)
Sample for USB CDROMs at R:
[DriveLetters]
DriveType=CDROM
Letters=R
Sample for ATAPI-CD-ROMs at L: and M:
[DriveLetters]
BusType=ATAPI
DriveType=CDROM
Letters=L,M
If no DriveType is configured then the default types are used. These are REMOVABLE or FIXED.
If all drive types shall be valid for a section, then you can use "ALL".
Sample to get USB drive letters for members of the admins group only:
[DriveLetters]
UserGroup=Administrators
Letters=X,Y,Z
;no USB drives for all others
[DriveLetters]
DriveType=ALL
Letter=--
Do not configure like this:
;all others
[DriveLetters]
BusType=ALL
DriveType=ALL
Letter1=-
This would remove the drive letters of all drives, USB or not, because of BusType=ALL.
