Hello,
I'm not sure what you mean by "upgrade the dongle". Upgrade the driver, or replace it with a different piece of hardware? Something else?
Why can't you upgrade it? Any error messages?
Please take a screen capture of your AnywhereUSB Configuration Utility and e-mail it to jmcbane (at) digi.com. Before taking the screen capture, click "View / Driver Information" and drag that window to the side so I can see it as well. To take the screen capture, press the Print Screen key on your keyboard then open Microsoft Paint (start, Run, "mspaint", OK) and paste it in there, then save it as a .jpg.
