I just got a SDS 100 and can't even get mass storage to work. I am using my wife's pc since I only have a Mac. I have previously attempted to enter numerous favorites onto the Sentinel software but I can't even get mass storage to work. I plugged the connecting cord into the usb 2 connection on the scanner. It doesn't appear that the cord will fit into the usb 1 port. I have tried connecting the other end into 3 separate usb ports on the pc. When I turn on the scanner and enter E, the mass storage language comes on but nothing happens. When I go to control panel and then devices on the computer, the computer indicates that it cannot recognize the serial driver on the SDS 100. Any help would be greatly appreciated.
