I'm writing in ref. to step (3) on your instructions. I don't know how to get your email address to email you a request for this but I'd sure like to know how to fix that issue. (Keyboard HID device is generic rather than Logitech - therefore cannot update keyboard HID driver per your instructions.)
Believe it or not, I'm an IT "specialist". 'Been in the field since the dark ages (DOS...). So, I know my way around pretty well. But I gotta tell ya, this problem has me climbing the walls. I finally broke down and called Logitec support this a.m. and spent more than an hour on the phone w/ the rep (who was very nice and courteous, btw) mostly repeating things I'd already tried (using what I'd found on forums like this - and your posts).
We got Setpoint back to providing a "My Mouse" tab again. Basically by renaming the wdf01000.sys file in ...\system32\drivers. (OS=XPPROSP2). I'd done this b4 but I uninstalled Setpoint b4 reinstalling it. When I tried this w/ the Logitec rep, I was instructed NOT to uninstall Setpoint 1st - rather install on top of it. So, I did and, lo' and behold, it worked - I got my "My Mouse" tab back.
In an effort to get the keyboard tab showing in Setpoint, I had uninstalled then re-installed (no cleanup, etc in between) the Setpoint software. After that, not only did I still have no "My Keyboard" tab in Setpoint but I'd lost the "My Mouse" tab as well.
I'd already had to restore an image of my hdd because, b4 this, I'd screwed around w/ Setpoint, dinkin' w/ files and the registry.... Well, it was a mess. So, restore was the next course of action. (Thank gods for ATI!) Then I begain again w/ the sequence of events I described previously.
Logitec swears up and down that there is no Logitec HID driver for the Alto wireless keyboard. That all the "special functions" marked on the keys are Industry standard key stroke combinations. Well, I beg to differ OR there's somethin' amiss on my system. I can't get any of these function key combinations to work. (e.g. FN + F1 should open explorer; FN + F2 should open the default email client; FN + F3 should open the default browser, etc. etc. None of them work.) Nor do the sound buttons work (increase and decrease volume and mute).
I'm convinced I need the Logitech HID driver for the keyboard. If I'm wrong, please, someone tell me. But tell me how to fix it, too, please, if you can...
So, my friend, if you could p-l-e-a-s-e send me that fix I would be ever so greatful!
