|You're obviously connected to the Internet if you're reading this on the netbook. |
Perhaps there is a firewall issue with Windows Update. Check it out in the control panel. Of course, the system would be screaming at you if Windows Update wasn't working properly, but please check it anyway.
Whatever is happening, the software is not loading on your computer. Usually when hardware is found, it checks the computer, and then removable drives (but you don't have those, b/c it's a netbook... maybe you do.) If the software is not found, it connects to Windows Updates, compares your hardware to a database. If a match is found, the software downloads and installs. This happens in a few seconds.
What I'll bet is going on is that you're running a 64-bit version of Windows and the drivers for the mouse are not compatible with 64 bit Windows. So far, I've only seen this with very cheap knockoff Chinese stuff on Ebay, and the Palm HotSync cable/dock. Palm really is on the cutting edge, you know.
Check to see if you have 64 bit windows on your computer. Right click Computer, and select properties. You'll see in the window towards the bottom if it says '64-bit operating system.'
Whether or not you're running a 64 bit OS or not, go to the HP website to determine your hardware's compatibility. I'll even provide you with the link:
Enter the full name of your product in the search box of the page, select downloads and drivers, and download the appropriate SoftPaq for your system. Install it, and try again.
Best of luck.
