Help - Harmony3 USB example on PIC32MZ2048EFM100 custom board

Hi All,
PIC32MZ2048EFM100  custom board
I want to implement a USB(dual_CDC_ACM) to serial converter for uarts  U1,U3
I am starting out with Harmony3 USB apps as basic reference.
The Harmony3 usb demo apps support the EFM144 proc, so not applicable to my custom board with EFM100
I attempted to change the proc to EFM100, but my attempts seems to fail on enumeration on host.
(The host does not detect usb activity, so it appears no negotiation takes place, so usb does not register on host,
   hence no enumeration)
Is there anyone who have done similar and is prepared to share example code snippets,
pointers or basic example project to demo usb (cdc_acm) implementation on a MZ2048EFM100 proc,
either without Harmony, or with Harmony3,  else Harmony2?
Thank you for your feedback -
