Hi:
    I want to create 4 virtual com port through USB on LPC1768 chipset. I have rewrite Configuration Descriptor and some EP_IN/OUT function but my PC only can only enum 2 virtual COM port. Can anybody tell me why PC only enum 2 virtual COM port? My system is WIN7 x64. The attach is the picture of enum result.
  thanks.
