Cerbuino + CDC

Do I understand it right that the Cerbuino doesn’t support CDC under .NET 4.3?

@ User_8034 - That is correct. The cerb family does not support USB client.

o.k…
I found the article “Communicating with your MicroFramework Application over USB” https://guruce.com/blogpost/communicating-with-your-microframework-application-over-usb where I can manage this over the .NET framework. But my problem here is that the USB is detected, but that the USB controller is in use. I think it is because it is in debug mode.
Is it possible to switch the debug interface to a serial port so that the USB controller becomes free?

@ User_8034 - If you are still using the Cerbuino, you cannot use serial debugging. See https://www.ghielectronics.com/docs/46/fez-cerb-family-developers-guide#399 for what is support on the Cerb-Family.

Is there no possibility to use the USB-Port? For example switching off debugging?

6

@ User_8034 - Not on the Cerb-Family. You can either use USB host or debugging over USB client.

But I think I can’t connect the USB host port (big one) to a PC for data exchange?

That means I have to use an external USB client module. Is it possible to use this module https://www.ghielectronics.com/catalog/product/330? It is cheap and I don’t need the Gadgeteer capabilities. So I could connect it to COM2. COM1 I need for my application.

@ User_8034 - It is not. That module is only used to expose the existing USB client functionality of a product.

If you need serial communications with a PC, you can look into https://www.ghielectronics.com/catalog/product/287 and https://www.ghielectronics.com/catalog/product/437

or any cheap/alternate TTL USB-Serial module if you’re OK using connecting wires instead of a full module. I like the CP2102’s that are mega-cheap on ebay and have decent drivers, like this one http://www.ebay.com.au/itm/Practical-USB-2-0-to-TTL-UART-6PIN-Module-Serial-Converter-CP2102-STC-PRGMR-E-/261484597085?pt=AU_CablesConnectors&hash=item3ce1b24f5d (edit: if you buy these, buy 5, you’ll always need another one sometime and won’t be able to easily lay your hands on it or extricate it from your other projects)

Hello Brett and John,
does this devices act as a UsbController? Do I get this with this command:
UsbController[] controllers = UsbController.GetControllers();
?

@ User_8034 - Do you mean a USB host controller?
