[SOLVED] Connect yun mini usb with yun USB A does not work.

Official Hardware Classic Yún

Hi
As I have a sketch that uses the serial communication that I want to run on the yun. My original idea was to port the code so it uses the bridge.
Then I got the smart(?) idea to simply connect the usb of the leonardo with the usb of linino. This way I could continue using the serial communication via the usb ttyacm0 and have the bridge do the more advanced web stuf.
Connecting the 2 usbs did not give any sparks. but the dmesg doesn't look good:

[ 2637.840000] usb 1-1.1: new full-speed USB device number 4 using ehci-platform
[ 2637.970000] usb 1-1.1: New USB device found, idVendor=2341, idProduct=8041
[ 2637.970000] usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 2637.970000] usb 1-1.1: Product: Arduino Yun
[ 2637.980000] usb 1-1.1: Manufacturer: Arduino LLC
[ 2637.980000] cdc_acm 1-1.1:1.0: This device cannot do calls on its own. It is not a modem.
[ 2637.980000] cdc_acm 1-1.1:1.0: ttyACM0: USB ACM device

This device cannot do calls on its own? I guess there is some configuration error somewhere.
Any input on how I could fix this or why I should not do this is appreciated.
Best regards

You can ignore that message.
It only means the USB device is just a simple serial line, not a modem.
If you connect the Yun to a linux pc, the pc will give the same error message, but you can of coarse perfectly communicate with it.

well I only checked dmesg after I failed to connect with the tty with minicom.
So this may not be the root cause but there sure is a problem somewhere (even if it is only in my head :fearful: )

Seems the problem was located with me.
Works great now :slight_smile:
