Serial port COM11 is not found!

NI$HANT:

If you have tried all these suggestions already but they didnt work then have you tried to do something with the ATmega8u2 or 16u2? I mean reading the fuses etc or trying to connect a ISP to it?

Hi;
Thanks for your response :slight_smile: and sorry for being late in reply, but I was busy with other projects and assignments.
What do u mean by ATmega8u2 and 16u2?? could u explain to me what are these??
