Hi Michael,
The image attachments did not come thru. You might just try attaching them directly rather than inlining them in html.
What I had wanted you to try was rebooting the device and computer, then try WIA right away before trying HPPSDr utility. My thought was that all the tests that PSDR does for some reason gets the WIA service in a bad state such that scans don't work until the next reboot.
