Making a USB based Data logger using P18F4550.Confusion Regarding Software Resources.

[hassanzia]

Hi all. I'm trying to make a data logger utilizing USB interface using a p18f4550. My requirement is that the data converted by the PIC's ADC would be available in MATLAB. I need help regarding the following

- I'm confused as to which driver to use in the firmware. Should I go with the HID drivers or the custom MCHPUSB drivers by Microchip.
- Which of the Demos in the Microchip Application Libraries would be the most likely to help me? I tried understanding the demo of "USB Device - SD Card Data Logger" but I think it is tailored to writing on a FAT file system
- Is it possible to import data directly into MATLAB (like one can do with incoming data on the serial port) or would I have to first write the data sent by the controller into a file?

Plus any helpful links/articles which can help me in building this application would be highly appreciated.

Thanks

Also this project is good. Project uses ATMega32 8ch ADC monitoring of voltage/temp and all data is logged to SD card :
