Hi nanalexandru, I noticed your profile and would like to offer you my project. We can discuss any details over chat.
I would need to be reading an SD card from a Teensy board using Freescale commands or Arduino.
The connection between SD card and the chip is made through a card reader, which supplies power over the USB port to the MCU & the SD.
I believe this to be below your skills, but would appreciate your action.
