Post subject:  Cannot manage NEO with neoman, etc after disabling OTP

I use my neo almost exclusively as a smartcard. So I disabled OTP and U2F, leaving just CCID. Now I can't get back into the neo to revert these changes. The CCID USB device has a different product id than it did before "0112".

Thanks!

See https://www.yubico.com/2012/12/yubikey- ... te-device/

Specifically the part that says "Be careful, you can use the -m command to remove HID support; as ykpersonalize only works with through the HID interface, this means you cannot use ykpersonalize anymore if you remove HID support"

"ykneomgr -M0" should fix it.
