I’m using Banana Pi R2 to connect health care devices usb ports of Banana-pi R2. I’m sending and fetching data from that device via usb from Banana-Pi and Banana Pi sends these data to the server accordingly. After some hours, usb connection cut and USB port disappears. Moreover, lsusb command does not show that device. I have to plug out and plug in that usb or restart Banana-Pi. Do you have any idea why is that problem happens? Any solutions to that problem? Anything happened and resolved like that problem? You can examine my command line via ssh.
You could try another image/kernel and looks if the problem also exists there. and/Or you can check solder-points of the usb-port
