Pete,
Have you tried running the NI-488.2 v2.4 installer and clicking "Repair"? After that, hopefully you would be able to do an uninstall of 2.4 so that you could get back to 2.2. I know it's a multistep process, but it seems like the best way to get some results for you.
I also hear your complaints about obsoleting hardware. We are forced to make decisions for technical reasons and we do occasionally have to obsolete older hardware when a new driver releases. In an ideal world, we would support all hardware even from way back in the 80's in our newest Windows XP (or soon to be Windows Vista) driver. However, the number of technical issues with doing this is huge. For example, the testing burden alone for the 30ish GPIB interfaces we've had over the years, some of which are created for buses that no longer have Windows support, would delay the release of new drivers for months and maybe even years. We run extensive tests on every supported interface before shipping a driver to ensure that it is of the highest quality. Taking a long time when customers get a new OS like Windows Vista is clearly not a good thing. It is sometimes necessary to obsolete old hardware to allow us to move forward with development.
Please let me know how my suggestions turns out. We'll get you back to v2.2 so that you can use your USB-A.
