Yes I have tried it in several different USB ports to which work with other USB devices.
My device is the one pictured on the left side of your photo, it has a detachable pigtail USB cable that came with it, plugging just the Video Capture USB device without the pigtail into the USB port, still does not work. The service Pack package you linked to, I have already tried because when I clicked your link above, it gave me a file called vhstodvd_sp3_to_88a (1) which indicates it has already, previously been, downloaded and I ran it already, but I tried it again and there was no difference from the first attempt.
Here is a screen shot of my device manager with just the USB dongle (Minus the USB pigtail cable extension) in the USB port. It is pressed in as far as it will go. Worked fine with a test on an older Windows XP 32Bit Dell computer USB port. It showed up as 'USB 2861 Device' in XPs device manager, as you can see below no 'USB 2861 Device' listed. (oh, to keep you on track I still have and used the original installation CD that came with my capture device, it installed the software and I entered my valid product key and the software install went flawlessly and loads when executed.) (See my screen shot of my software loaded on screen and the version number below)
