Seneye USB timeouts #1
Description
In some cases this error is thrown. I've updated the code to open and close the USB device in the update statement, which works fine when the device is only reading every 30 mins but is overkill for when light readings are implemented. Leaving here for tracking, for when that change is introduced.
