I know this is probably not the proper newsgroup to ask this question,
but I do not know which one is. And most of you guys here know a lot
about windows programming so I am taking a chance some one here may be
able to answer this simple question.

If I burn a CD/DVD and include a file in the root of the burned disk
called Autorun.inf and the contents of it is:

[autorun]
open=C:\Program Files\myProgram.EXE

then when the CD/DVD was inserted in the drive, the program at
C:\Program Files\myProgram.EXE would automatically launch.

I would like to do this same thing on a USB Flash drive. I have tried
it but it does not launch the application.

What is the magic incantation?

Google is your friend, try searching: enable autorun usb flash drive

Most USB drives don't support it without software installed on the
computer..

Q: What must I do to trigger Autorun on my USB storage device?
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. A 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.

For more information about the StorageDeviceProperty, see the
STORAGE_DEVICE_DESCRIPTOR storage structure in the Windows DDK, located at

For more information on Autorun.inf files see the "Creating an
AutoRun-Enabled Application" article located at
