I program with LPC2368 on ARM7 architecture and will configurate usb coonection with my pc. After initialization periphery and clock, i try to start usb. I am using the following scheme fro pull-up resistor in line D+:
For connection this pull-up, i change voltage-level on pin UCON from 1 to 0. After this i receive reset signal from host and message GET_DESCRIPTOR. Then i try to reply on request, but controller nothing sends. I think, problem in hardware. Maybe needed disconnect pull-up resistor after detecting my device?
