I am working on LTE USB modem driver installation.

While plugin USB device it detect as CD-ROM and we need to switch it to USB modem before installing windows modem driver on the device.

How does one go about executing a USB switch mode on Windows?.

I found it can be done using DeviceIOControl() IOCTL_SCSI_PASS_THROUGH_DIRECT. But I am unclear as to what values need to passed in struct SCSI_PASS_THROUGH_DIRECT.

Is there any other method to do USB mode switch ?

Otherwise, what values need to pass in scsi ioctl?

The contents of structure would be device specific. You'll have to ask the manufacturer of the device. – Ross Ridge Dec 07 '15 at 06:38
