I recently upgraded to the latest version of Hyperion and now my Lightpack LEDs are annoyingly flashing white and flickering periodically. I am using the same config as I had with the older version. The colors and motion seem to be otherwise working normally. This setup was working perfectly for over a year prior to the upgrade. I noticed in the logs the following messages repeated over and over: Oct 27 06:50:14 raspberrypi hyperiond: Unable to write 61 bytes to Lightpack device(-9): LIBUSB_ERROR_PIPE Oct 27 06:50:19 raspberrypi hyperiond: Unable to write 61 bytes to Lightpack device(-1): LIBUSB_ERROR_IO I am using a Rasberry Pi 1 running Raspbian Stretch with two Lightpacks and the latest Hyperion / HyperCon. Is there any way to reinstall an old version of Hyperion to see if that might resolve the problem?
