  1. nice post but idont know acceptable 4 my place?

  2. I love you. If only I found this article sooner...spent about 42383245 hours tinkering with the Dlink Drivers.

  3. Thank you - after futile hours spent trying to get the DPH-50 to work the US Robotics software works perfectly!Rather than remove the other dirver, I went into tools and simply disabled it there.


  4. OMG!!! Thank you! Thank you! Thank you! Trick #2 worked from the start without installing the D-Link drivers! Thank you!!!

  5. I tried both approach. But Windows 7 won't let me modify the driver (update driver option is shaded). Any indea?

  6. Upon plog in the box, Windows 7 didn't offer to ask about the driver. It just finished. How to set the Windows 7 not to auto install?

  7. Okay, I figured out the part of how to update driver. You have to click on [Change Settings] before clicking on [Driver] in order to enable the option.

    Now I got the adaptor to access the Skype, which ask Skype for permission of "VoIP Agent.exe wants to user Skype". After I click [Allow Access], the icon turns green. Great!

    However, the computer speak didn't turn off...
