Hi Bhuvanes,
I supose you are talking about Device Instance ID in DLP solution, or am i wrong?
If so, to find that value repeat the process above and select Property "Bus relations" in Details drop-down menu.
In my case and as an example, in DLP solution i have:
Device Instance ID "USBSTOR\DISK&VEN_SCSIDISK&PROD_SCSI_DISK_1234&REV_1.00\201403201134003000003432&0"
and in Details-> Property "Bus relations": USBSTOR\Disk&Ven_SCSIDISK&Prod_SCSI_DISK_1234&Rev_1.00\201403201134003000003432&0
Regards.
