I want to find a simple and quick way to permit my application to bring a file located in my file system and write it into an external USB device. I have to use Bulk Transfer Only mode that means to use stream of characters only. I looked through the LibUsb library using it in my IDE I can transmit a string.
To transfer a whole file I suppose I've to dodge the file system building a char sequence that permits to recognise a file in the file system and to put it into the usb device.
Note I'm working with Ubuntu 10.04
