Windows 7 allows running old XP devices in a XP virtual machine. You can download MS' virtual pc with XP mode
here. The magic in getting this to work is to have your Logitech IO2 digital pen in the cradle and have the cradle plugged in to your Windows 7 usb port at the time you install the virtual machine and install XP from a XP CD. After you do all the usual updating of XP w/in the virtual machine, you can download logitech's last (RIP) driver for the IO2 digital pen
here. Press the 'External Mirror 1' link to download. Also, be sure to click the 'USB' down arrow in the upper left hand area. You'll see 'Digital Pen' as one of the USB devices. Click the gray area to the left of that entry to activate that USB device so that virtual XP can see it. That one cost me much head banging.
Here's a screen shot of my I)2 pen uploading 5 pages to the virtual XP machine running on Win 7.
