Pizman,

Excellent idea! I will try it in the next days (Tomorrow I have to help my daughter moving to a new house)

Gentleman,

This threat can be closed, but before that is done I have to inform you about the final results.

First: the Arduino is now functioning fine in combination with the MF software and is it doing what it is supposed to do. So, I am happy.

A short summary about what happened since my last post:
Last information was that the second Arduino looks functioning well. However after several cold restarts it had the same behaviour as the first one so I concluded that most likely it has nothing to do with the Arduino Hardware.
To be sure I reinstalled the software on the first board as suggested by Pizman and did some testing with a lot of cold restarts with both Arduino's on a second PC: no problems.
Then I disconnected all the connections (mainly P & P radiosets from Open Cockpits) to the USB hub in the pedestal (Sitecom, ext. powered), cleared the USB connections in Windows too and connected only the Arduino. Even after a lot of cold restarts the Arduino was well detected by the MF software.
As soon as I connected the other USB units in the pedestal the problem was back. So I decided to connect the Arduino to another USB hub (same model, but outside the pedestal) and all was and is functioning well.
What the reason is for this behaviour: I don't know, probably I do some other testing in the future. For the moment I am happy and know that at least the Arduino's I have are for some reason sensitive for the way they are connected to an USB hub.

I am grateful for the support on this forum. Thanks!

Hans

Nice it workes !
I will mark this thread as "Solved" !

Note:
Maby this is interesting, too. With pasing time we got even more users that work with a real big and complex cockpit..... These problems can´t be seen if we only use 3-5 ardionos.
Maby in future we can make a guideline like " Not use more then x Arduinos on one USB Hub" or "Not connect Arduinos and PlugAndPlay Controllers on SAME Hub"

Maby a Engeneer for electronics or a Professional System Administrator can comment this, too. I Always thought it´s no matter if i connect a Unit into a Direct USB Port or via a Hub.
Let´s wait for more reports if this come again...... So @ALL Please report every issue that occores from USB Hubs !

Hi,

I have just had a similar problem with a powered hub. I bought a new hub so I could plug all 3 of my Arduino Mega (clones) into the same place, but they refused to work in the powered hub - they all work fine in a non powered hub - so I assumed there was a fault with this new hub but after finding this thread I wondered if the comment that all connected devices should use the same ground could be the problem. The PC is connected to 1 plug board - the powered hub in another plugboard.

Now both these boards are connected to same same ring circuit so I assumed they would be grounded the same via the earth cable.

So I tried connecting the powered USB hub into the same plugboard and the cards were connected. Not sure why this would be but anyone having these non connecting issues with a powered hub should give this a try.

Hope it helps

Dave

i got same problem. led yellow ligh behind pin13line up.
firmware n/a
com port 3
serial n/a

fazli.....

Your not a new user and know the procedure.

Give us ALL needed information !
How many boards do you use ? Are all rpoblematic or still one ? Is the whole board problematic or only devices on special Pins ?

If you guys report a problem then please NOT make a 3 line report mith less then 160 chars like a SMS ...... Tell us much detailed as possible what is happend..... then we can help you !
