hi, i changed the USB code that made for Keil to GCC and compiled with it, the LPCUSB.rar is compiled version with GCC and the other one is compiled by Keil, i changed the target.h to use USB but not working yet, please someone test my code to get it working, thank you very much.
i think i found the problem, i think i must add the usbram to lpc2378.ld but i don't know how and i found this inside the freertos example for lpc2368.
