If so, you are not alone. Both options work for me, however it depends on which cord I am using. I came acrross this other way to do it also, using a different driver. You many have to re-do the above steps if you re-boot the PC or do a windows update. You should be able to communicate with the radio fine now. Once complete, click on Close, and Close again, and the Device Manager should now be changed to: Select the older 2008 version as shown below. Then, go back to the Device Manager, right click on the above line, select properties, go to Driver tab, select Update Driver, select Browse my computer for driver software, then navigate to the downloaded file, then select Let Me Pick, then you get a selection as per the picture below. Unplug the USB cable, and plug it in again. Once downloaded, open the zip file and run the exe file and install. However you go to you can download an old driver version, then install the old driver version. What windows have done, is for the older chips, Window’s has dropped driver support for them.

While this is all very informative, it really didn’t help me.

This same issue happened to a USB Card reader also. I went into the device manager and found the error, my cable no longer worked.

You can see more, import more and adjust things quickly. I like to program my radio or scanner via the computer.
