Problems with port recognition

Development Tools IDE 1.x
1

Hello guys,

I am having trouble with arduino recognizing the port connected with my laptop. Arduino Led is green and I changed several times the USB cable and it seems to be working fine.

Whenever I hit the device manager, the port LPT section is hided and when I choose the option to show all hidden devices, it show up the port LPT section but in a 'ghosted' way. Same when I open arduino softwares and in the tool section the port option isn't 'clickable'.

Mine is arduino mega 2560 (3d printer stuff), would you guys know what is happening?

Thanks, sorry for bad english.

Try the Loopback test, see if the USB/Serial chip and drivers are working correctly. There's a Sticky top at the top of this forum.

Isn't it a clone? Try the CH340 driver:

I have two windows 7 and they do not see anything in device manager as com/lpt port does not show up at all. Have tried drivers and nothing works. I also have mac 10.9 and it does not see the board. I have a uno board got from ebay and the old thing that sees it is my very old XP computer and I do not want to keep using that. So how many hours and days does it take to get it to work and new computers? Any new links for getting windows 7 to see com port. It seems that MS will not help out to fix it but with all the others out there trying to get it to work you would thing it would be easy. Just about ready to throw it all out. I'm a new be to this but not to a lot of other things.
Thank you for any real help.

So why not answer the question about it being a clone? Have a close look at the chip next to the USB, what does it say?

And apart from not showing up under COM-ports, is there somewhere else in that list a device marked with ! in front of it?
Doe you hear the USB connect sound when you plug in the board?

And do I understand correctly that you have a Uno as well (besides the Mega)?
And you try to say it only works on Win XP?

The problem with most Arduino's isn't that Windows doesn't want it to work, it just doesn't have the driver for it or the manufacturer of the chip doesn't want it to work.
