Hello Cuentin,
No idea. If by pen drive you mean those USB memory sticks I heard that it was quite difficult. There are micro controllers with built-in USB features (TUSB series from TI?).

Have anyone accessed to a usb pendrive using a microcontroller? How can I do it? If someone have used a usb pendrive with a microcontroller please help me. Thanks and sorry by my english.

There are vendors that have such things for embedded processors.
Search for "embedded usb host" or similar.
