I just received the PICkit 2 from buy.Microchip.com.
To my surprise, the firmware source code and the PC host application
code (using Borland C++ Builder V6) are available in the
x:\Unsupported directory (x is the cdrom drive).
Sorry for the cross posting but I think this is good
news for the GNUPIC community as well.
I am going to try to port usb_pickit (Linux and Windows)
to the PICkit 2. I do not have access to Borland C++
builder anyway.
Regards,
Xiaofan

README
The PICkit 2 Operating System (firmware) source code was written
using the Microchip Full Speed USB code base. The source code
is compiled with MPLAB C18 compiler.
Unzip the file "PICkit 2 PIC18F2550 Ver. X.X.X 200X-XX-XX.zip" in
the root directory and rename the directory to "PICkit 2 PIC18F2550".
This will keep the project directory structure intact.

Version 1.0, Based on Jan Axelson's ####@####.#### USBHIDIOC V2.0
Implements PC to device communication via the HID driver.
Written for Borland C++ Builder V6
Access is through three functions:
WriteFile
ReadFile
CloseFile
Both Read and Write functions check to see if the device is opened on each
call.
If not, it goes out and looks for the device and opens the file. On
failure,
the channel is closed so it will attempt to reopen the device on the next
call.
bool WriteFile (char *buffer)
Assumes the contents of the buffer is correct and appropriate for the end
device. It adds on the 0 to the beginning of the buffer and sends it to
the HID driver, which formats it and sends it to the device.
bool ReadFile (char *buffer)
Returns the buffer read from the device.
Project: usbhidioc.cpp

Purpose: demonstrates USB communications with a HID-class device using
overlapped I/O.
Description:
Finds an attached HID-class device that matches specific vendor &
product IDs.
Retrieves the device's capabilities.
This application was created with Borland's C++ Builder 6's.
About overlapped I/O
Reading HID input reports is done with the API function ReadFile.
Non-overlapped ReadFile is a blocking call. If the device doesn't return the
expected amount of data, the application hangs and will wait forever.
With overlapped I/O, the call to ReadFile returns immediately. The
application then calls
WaitForSingleObject, which returns when either the data has arrived or the
specified timeout has elapsed.
