I've got the exact same problem.
I've got three Windows 8.1 computers, it works fine on two of them, but refuses to work on the third.
Device manager shows it as 'Microsoft USBccid Smartcard Reader' and 'The device cannot start.'
When I plug it into the problem computer, the green light on the Neo turns solid green (i.e. indicating it's working and ready to generate codes), however when you press the button the green light immediately turns of completely without sending anything to the computer (well, any text anyway).
The light remains off until you unplug it from the computer, and plug it back in again at which point the entire process repeats itself.
I've tried removing all USB bus drivers and rebooting as suggested, but it's still doing the same thing.
When you plug it in for the first time without drivers, the Windows 'installing new device' window pops up and identifies it as 'Yubikey NEO CCID'.
I tried changing mode to 82, and it sorta worked? I changed to 82 on another computer, booted up the problematic computer and plugged in the key. This time, two 'installing new device' windows came up, one talking about a Yubikey keyboard, and the other about a Yubikey smartcard (I think, I'm going from memory as they were only on the screen for a second). Once that completed, it actually worked. I was able to press the button and it spit out the code as expected.
HOWEVER, just to test it was completely working, I turned the computer off and back on again, and tried it again -- and it went back into broken. The 'Installing new device' went back to 'Yubikey NEO CCID' and didn't configure itself correctly. I've not been able to recreate my short-lived success again.
So, long story short, I have no idea what's going on. Any ideas?
Side note: What's the default mode for the Neo? Should I change it back to whatever it was before I changed it to 82?
EDIT: Also, no virtualisation software here either.
