got it also working on my mega2560 after some trouble:- on my debian in standard repository was only dfu-programmer Version 0.4.3. The at90usb82 device was not recognized (dfu-programmer: no device present) , although the device is listed when dfu-programmer is called with no options.- upgraded to dfu-programmer 0.5.2 from sourcereference: [removed - see original post]Code:svn co [removed - see original post]/dfu-programmer dfu-programmercd dfu-programmer/trunk/dfu-programmer/./bootstrap.sh./configuremakesudo make install - dfu-programmer now recognizes the at90usb82- erased with no error message- when trying to flash got the message: Something went wrong with creating the memory image- after some time of troubleshooting I found that the downloaded .hex file was wrong. I don't know why, but it was not possible to download the raw file with epiphany- downloaded the .hex file with wget, flashed it and it works perfectly.Smiley Reinhard
