I wrote single-core project on lpc4370 with USB (used lpcopen blinky, VCOM, USB1) and it is working smootly, but when i turned project into multi-core project is running into error (hard fault) when i plug in usb hub (if i not plug USB than no error). If i switch off M0 then USB working again and i don't know the reason.

With the limited information you have provided it is difficult to tell the exact cause - but I would imagine that the code/data for your M0 is overwriting memory used by the M4. Double check your memory map usage by both cores.
