Create dual cdc ports

I am trying to create a dual USB CDC serial port with my LPC1768 mbed board, I did some changes in the usbcdc.cpp, like below, but my Linux always recognize it as one ACM port, can't find another port, here are the codes, really appreciate your help

-- [ 789.250205] usb 3-2: new full-speed USB device number 5 using xhci_hcd [ 789.379655] usb 3-2: New USB device found, idVendor=1f00, idProduct=2012 [ 789.379666] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 789.379671] usb 3-2: Product: CDC DEVICE [ 789.379676] usb 3-2: Manufacturer: mbed.org [ 789.379680] usb 3-2: SerialNumber: 0123456789 [ 789.380263] usb 3-2: Interface #2 referenced by multiple IADs [ 789.381918] usb 3-2: Interface #3 referenced by multiple IADs [ 789.383929] cdc_acm 3-2:1.0: ttyACM1: USB ACM device
