PROBLEM - Photosmart 7150 Install in Vista Home Premium 86x

I have installed Vista Home Premium 86x Upgrade within the last week. Things
went pretty well, but it seems that many drivers didn't automatically
install. This was true for my Memorex Traveldrive 1GB flash drive and
Olympus Stylus 800 cameras. In each case I had to have the machine first
tell there was new hardware, then there were [4] steps to finally actually
read the device. The [4] steps were the same step repeated (install driver
searching c:\\). After the [4] steps, the devices worked. When I installed
Vista Ultimate on my main machine, I didn't run into this.

I'm down to the Vista Home Premium driver need for my HP Photosmart 7150. HP
says there's a basic driver in Vista. The only drivers I find are DesignJet
drivers, nothing else HP. I would be happy with basic connectivity.

Can anyone help me???
