Looking for the name of the Mega Driver!

Hello, I am new to programming. I have a Mega 2560 board and I keep getting a down load error " com7 not found or the board is not plugged in.

It looks like the fix is to move the driver to the Arduino installed directory. All of the Websites say move it but none of them say what the file name is! What is the name of the Mega driver I need to move?

Thanks ... Lou

What OS ?

Which links say move things ?

Clone or REAL arduino ?

Do you have the correct port selected from Tools -> Ports? It sounds like you had it working before (since you had at one point selected a COM7 as the port - and if you got up to COM7, you must have a history of using it...)

Windows will assign new com port numbers if you plug it into a different port, or occasionally for no apparent reason.

I have never heard the advise of moving files - that doesn't sound right, since you need to point windows to a driver, and the driver was already installed when you installed the IDE anyway. Is it a clone? Most clones use a CH340G serial chip, which uses different drivers, which you must download and install separately (it's not included with the IDE, since the official boards never used it)

I have Windows 7 64 bit.

This is the link that that said move http://drivers.softpedia.com/get/Other-DRIVERS-TOOLS/Others/Arduino-Mega-2560-USB-Driver-1110-for-Windows-7-64-bit.shtml

My Mega is a clone by keyestudio.

My Mega board driver (from device manager) is C:\Windows|system32\DRIVERS\usbser.sys

Maybe the problem is that the driver has to be changed. But I do not know the name of the correct driver.

OK Softpedia makes sense...

Those dont mention moving but MANUALLY installing a driver.
Which is a different thing altogether.

Also your driver is NOT USBSER.SYS as that is again another thing that looks after a lot of USB devices VIA the drivers (simplified explanation).

If it a clone there is a very good chance what you do need for drivers are THESE.
Its is a Chinese site but one most of us trust for those drivers.

The CH340/341 drivers are never included with the IDE.

You best bet is to use the "install as administrator" option under windows.
Disconnect anything that is using the USB or serial ports (apart from mouse and keyboard)
Install the drivers and for good measure do a re-boot.
Re connect your other items but not the board. That should be connected LAST.

It will then install a COM port that can be found under COM / LPT ports (hidden devices under win 10)

It should say CH340 COM x (X being the com port you should choose in the IDE.

Dont forget to tell the IDE which board you are using too !

I did it but I still have the wrong driver. Do you know what the driver name that was created from CH341SER.exe install?

Can I use the Device Manager Properties Window Ports(COM&LPT) to just update my driver with the new one. ...Lou

Why are you so insistent on the driver name ?

You can get to update a driver via Device manager and via a COM port but that is NOT what you want to do

I really would like a lot more details from as to WHY you need to do things the way you seem to want to do them ?

Also a picture of your board would be very useful right now JIC it is another USB chip on there.
A decent pic IN FOCUS close to the board.

I just thought that is how it is done if all else fails.

Here is the best picture my camera can take.

Let me know if there is a specific component or area that you need a better picture.

Thanks ...Lou

The picture did not send, it is too large. I will zip it ....Lou

Ballscrewbob, The zip of the photo did not reduce the file size. It is 2.5M! With your help and questions I found installation instructions for my Mega at keyestudio. I hope it works. Thanks.....Lou

You are most welcome Lou..

Just try not to do things then hard way next time :wink:
