Good morning, I have a Samsung Android mobile phone, what I connect via an usb cable to another device (not pc). For this case i have enabled usb debuging and the developer mode in android.

If I use another android mobile it works perfect, the other device is blinking and I can read out the device port by my android application. This "buggy" device cannot display the usb device port in my android phone and the bounded device is not blinking. For my opinion the device is not recognized by my phone. Is there anything else what I can change in the options or unblock? Is there some debug report oder anything else what i can look for what went wrong?

Thanks for your possible help
