In :http://www.matrixmultimedia.com/support ... f=20&t=537 the problem of the ECIO not progamming correctly is mentioned.

There are a few options which to look for, I have another problem.

Sometimes I manage to program the 40 pins ECIO.
When it does, and I use it later as a USB slave, I can only see the device as a COM port in the device manager.
In the list of USB devices it's gone.

I can see whether i'm going to be able to program it from the device manager view.
The ECIOprog doesn't see the device and it's not listed as a USB device (it does as a COM-port).

It's a difficult problem because sometimes it works and sometimes it doesn't.
Sometimes it helps to re-install the drivers and sometimes it doesn't.

The program pin on the ECIO always hangs on the USB pins..

I found a way to get the ECIO working.

I normally use Flowcode V4, when I open V3 and make an empty flow and send it to the ECIO, it works.
After that I use V4 again to send my new flow and that was successful.

Hope you can ever find the reason why this went wrong..

Hello,

I find that when using USB components on say the ECIO or MIAC you have to press and hold the reset button for at least 1/2 a second rather then a quick tap to allow the USB to reset correctly allowing the Matrix bootloader to fire up. Could this have been the cause of your problem?
