Code 10 error when installing Belkin F5D7050 USB Network Adapter

I'm trying to install a Belkin F5D7050 USB Network Adapter on my new-to-me Latitude C640, but I am getting a Code 10 error.  I have updated the BIOS and tried reinstalling the software several times to no avail.  The adapter works on my older HP laptop.  Belkin tech support says I have to call Dell.

 

Any advice would be greatly appreciated as I am quite frustrated.  Thanks in advance.
