The board is an USB Arduino Duemilanove with ATmega328.
While on windows 7, nothing changes on the device manager.. Even with the leds on the board going on the same way they do on the other PC. Absolutely nothing seems to happen on the pc, at all, when I plug the board. It seems hidden somehow..
On my PC with win XP a "unknown device" shows up on the device manager imediatelly after I plug the board (with the very same cable). Althought, when I try to update the driver with the softwares I listed above, I only got the message that no compatible driver was found..
I will look for another cable to try it out with the notebook and windows7, but since the connection seems to work with the xp, I dont know if thats the real issue..
As I said on another section of the forum, I'm not a informatics expert at all, but I tend to think my two problems are:
a) On the computer with windows XP, I couldnt install the driver because every single one I tried says to be incompatible.
b) On the notebook with windows 7, the board connection seems to be hidden somehow, maybe it is a view option, or a config for plug'n'play devices. Just because no icon next to the clock, nor driver request message, nor device ready, nor nothing pops up when i plug Arduino.
