Hi, I've encountered some issue running gekko on my orangepi.

I'm using ssh to access my orangepi and using screen/tmux to keep cgminer running after i log out the ssh session. Weird thing is, if I keep the ssh session running the cgminer works fine, but if i log out for a while, the cgminer will stop in mins and show "usb transfer err:(-9) LIBUSB_ERROR_PIPE 3476 Segmentation fault", and mining stops.

Could anyone help?
