Arduino Mega 2560 in DFU mode

Dear All, I´ve already installed and working my Arduino Mega 2560 board. Sometimes when I tryed to upload a program I get a timeout error (known issue as I coud read in several topics). What I did when I get this error, was just unplug the USB and reconect it again and upload the software again, pushing the reset button when it´s going to upload it. Whit this sequence, the problem was "solved".
Yesterday, I was performing this sequence, and when I repluged the USB cable, I get a Windows message to install the drivers. The new hardware that was foud was an "Arduino Mega 2560 DFU". When I tryed to install the drivers from the Arduino soft, the sistem was unable to install them because the drivers were not for that hard.

I´ve been reading several post, and it seems that the 8U2 chip is working always in DFU mode...
On the other hand, I´ve installed the drivers for this "new" hard, using the Flip software, and what I get when it´s intalled is a device under "Atmel USB devices" called "AT90USB82"

Please can anybody help me to solve this issue? Do I have to uplaod the 8U2 chip firmware?

Thank you

Alejandro

First of all, you should check the "official" topic about the issue, and just to clarify, we all tried to update that firmware...
If you wan't you could try it, there are tutorials online, and only thing worth mentioning is how to put it in dfu mode:
arduino.cc/forum/index.php/topic,53290.msg380874.html#msg380874
from there you just install drivers for the chip you have, then start flip, open USB, select device, load hex file from arduino hardware smthing, and burn it....

thank you! Regarding the official "topic" I did not found any topic related to this problem. What I found were topics with issues while trying to put it into DFU mode, but in my case it seems that the problem is all tbe way round...

Hehehe there are like 1 million themes with issues with the mega 2560. But follow xvjeko advice, he is switching to mbed because the mega 2560, so he knows what to try.

Dear xvjeko and Eried, finally it was solved with a firmware update!!! Now it´s working fine!!!

Thank you for your help!!
