hi

I am using LPC 1768 blue board.In that im trying to store data in USB.For that i took a sample code of USBHOSTLITE from NXP.I dump the code into my controller but i face enumeration problem.

I execute the code using JTAG,In that i observe program does not enter into

void USB_IRQHandler (void){} function.

And the code stuck at " while (!HOST_RhscIntr); ".
