Open source USB stack / Re: PIC18F14K50 not working
I was able to run this, with pickit2. Before i was using MPLAB ICD2. I think ICD2 is not directly compatible to program these devices. But, I was reading the programmed content, but somehow my chip was damaged, when I checked with pickit2. Thanks all of you for your guidance.

Open source USB stack / Re: PIC18F14K50 not working
Yes the 12MHz is the right crystal i guess. The PLL is fixed to 4, so we get 48MHz for full speed. I just took these config from Honken USB stack found in SVN (from file configWords.h).

Thanks for your reply.
I am using the following config: (derived from BPv4 - usb stack)
#elif defined(__18F14K50)
// configword 0x300000
#pragma config CPUDIV = NOCLKDIV
#pragma config USBDIV = OFF
#pragma config FOSC = HS
#pragma config PLLEN = ON
#pragma config PCLKEN = ON
#pragma config FCMEN = OFF
#pragma config IESO = OFF

#pragma config BOREN = OFF
#pragma config BORV = 30
// configword 0x300003

My schematics include minimal components like, 12 MHz external quartz crystal, 2x22pF across the crystal, 470nF across Vusb and Gnd; 100nF across VDD and Gnd. 10K resistor from MCLR (pin4) to Vdd (is it right for 14K50?).
Yes, I am writing and reading the memory and I can see the contents. Of course I can see different contents when I flash different firmware.
Do you see any mistakes in this?

Open source USB stack / PIC18F14K50 not working
I am new to this USB stack. Anyways i was reading all your threads and I was successful in running CDC in pic18f4550. But, I tried to use PIC18f14k50, i do not have any connection from the MCU to PC. I tried both Honken USB stack and also from microchip source code for this, but no success. I am just following the schematics from LPC of microchip and using MPLAB ICD2 (i think programmer works, but debugger will not work in this device). Also I am using the latest MPLAB IDE v8.56. I am struggling in this for nearly 3 days without any success. Could you please guide how to make this device to work?
Thanks in advance.
