Hi Ivan,
for the whole series 1-5, please include an lsusb -v or usb-devices 
listing for any device that you add support for.
What you find in device firmware or in Qualcomm SDK drivers does not 
necessarily reflect what has actually been manufactured and consequently 
  how those Id's could be used for a future different product.

The 1199:90d3 is already supported by the option serial driver and that 
is where devices with interfaces supported by their unique interface 
attributes belong instead of being supported by interface number in 
qcserial.

thanks
Lars
