I use Windows 7 Enterprise at home and it works for me
I don't have a issue with this at home.
Once I plug it in, a USB menu opens and verifies that it found a new device.
The issue you may be having is with in Vista itself.
I'm using Windows 7 Enterprise, and I can view all the files on my Asus, I don't even have Root yet. That whole .26 thing!
I just fired up a Ubuntu system at work to try to get around the issues with ADB on a Windows 7 64 bit system, so I can try to downgrade it to .17, root, load root keeper, then try the OTA update to .26. Have not quite got there yet though.
So far this has all been a complete pain on Windows, the ADB software comes to a screeching halt do to a Java issue, that no one can see to correct on my O.S.
Would be nice if some one just put out a 1 click Root app like I had on my DrodX!
