"The AutoRun capabilities are restricted to CD-ROM drives and fixed disk drives. If you need to make a USB storage device perform AutoRun, the device must not be marked as a removable media device and the device must contain an autorun.inf file and a startup application.
The removable media device setting is a flag contained within the SCSI Inquiry Data response to the SCSI Inquiry command. Bit 7 of byte 1 (indexed from 0) is the Removable Media Bit (RMB). A RMB set to zero indicates that the device is not a removable media device. An RMB of one indicates that the device is a removable media device. Drivers obtain this information by using the StorageDeviceProperty request.
For more information about the SCSI Inquiry command, see the T10 committee located at http://www.t10.org.
