Thanks Sam 2013, uninstalling both device drivers and restarting did actually do the job for now. Simply uninstalling the defective device driver doesn't seem to work though. I opted into this product and willingly accepted mediocre and sub-par hardware specs and lower build quality, but I definitely not opted into a product that requires constant maintenance and problem solving, constantly requiring to mess around with device drivers. That is a massive no-go in user experience. So, even if the AVN8 has unique value propositions in its Wacom digitizer -- which it has -- if that doesn't work reliably without hiccups, its benefits are moot and it certainly does not do what it promises. And I'm a computer scientist, who has reached the ends of his problem solving abilities. Imagine non-techie people dealing with this issue. I just see it as the old bane of Windows coming to show. Imagine yourself in a meeting, superiorly writing great looking handwritten notes on your AVN8 as your stylus quits on you and you start fiddling around in the Windows device manager, as your neighbour with his iPad leans over to ask what you are doing, and all you can return is that you try to fix the driver for your pen. It's a joke. Also, I received response from the German Asus tech support. Astoundingly, the guy mentioned that this issue was not known to them and all solutions he offered were generic steps to reinstall drivers and restore Windows. Will see if I'll follow through with that the next time my stylus quits. I really don't have the time to waste on stuff like that, especially if the outcome is questionable.
