    If you press the Refresh button on the Device Manager screen, the USB thermometer driver will unload (if it was loaded) or reload (if it was not loaded). Cypress is currently working on a solution to this problem. To work around this problem, do not refresh the Device Manager. If you must refresh the Device Manager, a second refresh will reload the thermometer driver.
