USB-USB File Transfer Module

Projects General Guidance
1

Good day everyone! I'm into study about making a USB File-to-File Transfer Module in which you can transfer file instantly. I would like to have it Bluetooth accessibility and a Touch screen user interface. But I have no idea how to start with it. The module must be smaller as possible. But I know Arduino and VNC2 products will be useful. Then, I would like to configure as, like, you can choose whether to transfer to the file to a Bluetooth device or to the output/input usb interchangeably so it does. Any idea?

  1. It's primary function is to transfer file from a USB Mass Storage Device to another USB Mass Storage Device without the use of a netbook PC or something. Through this touchscreen and handy module, you can transfer files through just a simple I/O connection or via bluetooth. (same principle as you were using a pc compying files from a flash drive to another flash drive)
    IT CAN COPY: A. from the input usb device to another usb device (output usb) or interchangeably; B. from the input usb device to a bluetooth device via bluetooth option.

  2. It must also be in touchscreen user interface.

So, that's it. I think it really needs a usb card or something, touchscreen and a bluetooth device right. and it will take a lot of programming.

I think this will help you to understand more, there's already an existing device. but it;s controls are just buttons and the all the files on a mass storage device are copied (everything) into another device. (i want this module to have the user the capability of choosing the file it wishes to send)

Start out by getting a USB host shield working. Arduino hardware is a USB slave, not a host, you have to be a host to access the big drives.

Seems to me that the easiest way to obtain all the resources you're going to need to solve this problem is to use a computer rather than a microcontroller - it would be much easier to solve on an RPi or an embedded PC.

The only Arduino that might even remotely be suitable is the Due. The rest are too small/slow to implement NTFS or transfer more than a few KB per second.

IMO, just move over to Raspberry Pi where Samba and NFS are easily do-able.
