USB vcp reset problem

I am using USB HS port in the FS mode in my vcp project. When I used it to communicate to  PC, it works ok if I re-plug in the device to PC. The problem is if I just reset the MCU from IDE debug, the device cannot communicate any more unless I re-plug in the device again.
I check the register, the USBRST in OTG_HS_GINTSTS  is always 0. Anyone has the idea what's wrong happened in the software reset?
