Issue Description

I tried to update firmware of my D415 camera using RealSense Viewer, but I failed. I got error popup message in RealSense Viewer like below text.

UNKNOWN in rs2_create_device(info_list:00000217AE13D200, index:0):
Failed to create FW update device, device id: \\?\USB#VID_8086&PID_0ADB#111111111111#{a5dcbf10-6530-11d2-901f-00c04fb951ed}

So I tried to use firmware update tool in RealSense SDK like below commands, but it also not work.
