Hi Manav, The LPC1768/69 has good support to USB Host, I used NuttX with a Momo Racer Force Feedback joystick almost 10 years ago: https://www.youtube.com/watch?v=z_-RAFdQd0s
Try to enable the Debug options inside Build Setup -> Debug Options using the "make menuconfig" to see where it is failing. Because LangTiger v2 doesn't have official support on NuttX and I never tested USB Host on mcb1700 board, it is better to use other board as starting point, i.e.: lpcxpresso-lpc1768. Also you need to get more used to NuttX and microcontrollers to get it done. So, please do your home work and spend more time studying about microcontrollers and testing NuttX.
