1. The windows operating system cannot handle USB devices being unplugged and plugged back too fast. When
unplugging the logger, wait for about 5 seconds before plugging it in again. If you unplug and plug back a device
too quickly, the computer may stop recognizing any USB devices on that port. If this happens you will have to
restart the computer. This is a windows USB problem and is not related to LogPro.
