Teensy 3 HID + microSD: Extracting files

[oriez]

Hi,

I would like to know if it's possible to use the Teensy 3 as HID and to be able to extract files from PC to microSD (connected to the Teensy device via the PJRC SD Adapter).
What I'm trying to achieve is a demonstration of a device that is capable to bypass DLP and other protection by using HID and that this will be able to write file from the PC file-system to the MicroSD on the Teensy.
Anyone tried to do it before?

when googling i found this site: http://hackaday.com/2013/01/26/extra...-with-usb-hid/
which doesn't help me much... no code or instructions.

The only thing that I know is that HID output the number that indicates LED keyboard lights to be on/off (CAPS,NUM,SCROLL).
I figure that using this might help me outout the file binary using the LED number and then convert it back to standard files format on the SD.
I think this method will be very difficult do and will run very slow (sounds good in theory...).

Anyone can suggest a better way?
