Before posting this question, I researched about the problem of ATMEGA2560 FTDI driver Installation in XP.
The issue is that the driver does not install at all. I tried to download VCP from FTDI website, still I get the same response. I use xp service pack3. Any advice
I do not know what mega uses. But I tried everything. At first I navigated to /drivers directory and nothing happened. Then I started downloading FTDI drivers, and nothing happened either. Please suggest workaround
Look at the chip next to the USB port, tell us the writing on it, or post a photo.
In addition to this - are you getting any indication that a hardware device is detected? IIRC even on windows XP, plugging in a USB device should produce a sound, and something should appear in device manager (likely with an error symbol next to it) when it's plugged in.
If you don't get anything in device manager, and no "hardware connected" sound, the problem is not drivers, it is hardware. In that case, check that USB port works, try with other USB ports, and try with a different cable (there is a plague of bad cables making the rounds which have power connected, but data connections are failure prone and sometimes DOA).
Tried everything as suggested above. Installed CH340 drivers. When I plug the USB cable, I get the message "found new hardware, arduino mega", then this takes me to the Hardware wizard to manually or automatically install the drivers. I tried all options ( to search automatically or give the path), but I get the message, "cannot install hardware" every time. BTW the symbol besides my USB port is seen as "8" or "infinity symbol" in another view. You may please not that this hardware is working with several other machines with WIN10. Hence there is no problem with either the cable or the board.
So why you've installed CH340 driver. ATmega16U2 is in genuine Arduino and it uses standard driver which is part of Arduino SW.
Versions 1.0.x work with XP pretty well.
