How to install in my computer the drivers of my BlackBerry?

I want to see the drive X and the drive Z in My Computers that is necesary to use Blend, Link and Sachesi. But when I connect my BlackBerry with the USB cable to my computer, the blackBerry desktop manager cant load my device, just inizialising but nothing happens... Its still working since I install the 2480 upgrade for my Passport. Now I can't use the Blend, The Link or Sachesi...
How can I find and install the driver of my Passport to my computer?

thanks for that link! I was pulling my hair out.

Thanks for the info, I am having the same issue (device not recognized by computer) and the only way I have found to solve it it's plugging and un plugging the device several times until finally gets connected... I hope installing the drivers helps in this regard, thanks!
