I have had the unit for a year with no issues with connecting to my dell xps with windows 7. While trying to update some programming, I was unplugging my scanner from its normal location and bringing it over to the PC and plugging it in through the USB cable and then unplugging and putting the scanner back where it sits connected to the antenna. I did the cycle a few times and on my last attempt to connect to the computer the scanner no longer asks about going into the mass storage device. I've tried connecting with all the usb ports of my computer and no connection. I have connected other devices to those ports and the devices connect fine. I bought a replacement usb cable through scanner master thinking something happened with the cable but still no connection. The unit just continues to scan. I'm afraid to ask this but did I break the scanner??
