Using the Wiki instructions for flashing the APM2 I am unable to connect to USB with the FLIP software.
After connecting to USB port and installing the jumper on JP2 port I use a wire to reset the Atmega. At that point I hear the USB disconnect/connect sound and the board goes to DFU mode. However I get a "new USB device found" message. In the device manager I see "Arduino Mega 2560 DFU" under "Other Devices". It's like there is no driver for this and it will not assign a USB port to it.
When I run the FLIP software and try to connect via USB I get a "Could not open USB device" message.
I have tried this on two different computers with the same results.
Anyone tell me what I am doing wrong?

Does anyone know how to Do this flash using a isp programmer. My apm is not seen in windows at all and i cannot get it into DFU mode. any ideas?
So the computer pretty much told you what's wrong, you need the driver associated with the hardware detection (AKA Plug-n-Pray).
Like every Arduino IDE, there is a folder with the install containing the required driver file (AKA .inf file)
"C:\Program Files (x86)\Atmel\Flip 3.4.5\usb\atmel_usb_dfu.inf"
Your folder may vary slightly.
So, in device manager, right click on that device, update the driver by browsing to the Arduino FLIP install folder (usually in the programs folder, but in win7, there are often 2 of them).
