que tipo de dispositivo USB es?, la ejecución de archivos autorun.inf
están restringidos a unidades de CDROM y discos "fijos", para que
funcione ese archivo en un dispositvo USB se debe marcar el mismo como

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. This link leaves the
Microsoft.com site

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

AutoRun-Enabled Application" article located at
