High likely an hardware problem, device programmer problem, or both.

Install USBDeview, with it, uninstall the generated PIC18 USB CDC device, then reinstall the "driver".
How would i know if it is a device or programmer problem (I'm using a JDM programer) http://www.instructables.com/id/Busi...IC-Programmer/
and using a winPIC programmer software.

And for the use of USBDeview, there is nothing there with regards to PIC18.....

Thanks
