Hi,
I've installed dfu-programmer using 'sudo apt-get install dfu-programmer' inside Ubuntu 14.10 and it seems to have installed correctly as I am able to bring up the --help file for it. However, for some reason when I connect a board to a usb port and attempt to put it into dfu-mode, it doesn't seem to work. The LED on pin 13 flashes a little suggesting the board is responding to the pins being shorted but when I attempt to run 'dfu-programmer atmega16u2 erase' it says: 'DFU-Programmer: no device present'. I have tried this with a number of boards including a MEGA ADK, a MEGA 2560 and an UNO R3. None of them seem to work. Also, I have installed libusb-1.0 as I thought that might help but it hasn't changed anything.
ANy help here would be massively appreciated
Thanks
