Zune not working on Desktop USB
I was not able to setup my Zune device since I bought my new desktop PC.
I downloaded and installed the latest version of the Zune Software, removed and reinstall Zune driver, nothing worked!
Symptoms:
- Connect Zune to the PC with the USB cable
- Zune software launch
- Get the message : "Searching for device..." and then...... nothing happens!
No way to find out why!!
Tonight I found the solution : I plugged my Zune through an external powered USB hub (and not directly on the computer) and now... it works like a charm!
My USB ports are working correctly, but I suspect them to not supply enough power for a Zune...
