Beagle Bone Black Log in issue via USB port


Beagle Bone Black after login via USB using PuTTY then disconnected from the USB port and wont allow to log in agian
Recently I am using 8.6 IoT Debian image with 4.4.113-ti-r147 kernel configuration.

Every time when I log in the BBB via USB port, it does allow me to log in but after 10s I was disconnected from the BBB console port via USB. I still able to log in the BBB from the Wifi or Eth0 interface. Does anyone know why this could happen.

Try using the network login and have a look at the log files.

Hi,
Before I plug the ethernet cable, I was performing the command dmesg and I found this:

[ 44.407262] gpio-of-helper ocp:cape-universal: Allocated GPIO id=0

I think there is something wrong with the cape manager

usb0 is the one I use to log in the BBB via USB port.

OK, so you have a USB networking adapter? Is it wireless? Which make and model?
