  • Check in Task Manager the amount of memory before and after opening the USB scanner.   Also try connecting the scanner to a different USB connector on the computer.  You can also open Device Manager and check the status of the Scanner to see if it is yellow.  Sometimes you just have to turn off the computer and turn back on.

    Does the MoxaN Wifi work with other USB devices?  Maybe a firewall or virus protection program is blocking the device.  Windows 7 & 8 may also block these devices.
