Hello,

You should be able to reset it, but a few steps are needed:

* edit /etc/libccid_Info.plist

to the array ifdVendorID add (at the top):


to the array ifdProductID add:


and to the array ifdFriendlyName add:


* After this, either restart pcscd (/etc/init.d/pcscd restart) or reboot.
* Now the YubiKey NEO should be recognized as a smartcard, if the light is mostly off you need to touch the button to "insert" the smartcard.
* Then run ykneo-modeswitch -m0 to switch it back to OTP only mode.

Also, what version YubiKey NEO have you got? (so I can test the exact same thing..)

/klas

Cool that worked.


Firmware version 3.0.3

Cheers,

Nils

Has anyone managed to get this working on OSX? I got it compiled, and it *almost* works, but not quite..

$ ./ykneo-ccid-modeswitch -m0

I've tried killing scdaemon, which doesn't make any difference.. if I kill pcscd it stops working altogether.

BTW.. looking at the code.. why do you ask Commit? (y/n).. it doesn't matter what you type, it commits anyway :p

does this help viewtopic.php?f=26&t=1088

?

That's just getting opensc etc. working.. that's already working fine.

I'll try again using a VM.. There's a nonzero chance the key is bricked (it went into ccid mode on its own without any application of ykpersonalise).

Didn't get anywhere on a VM.. tried a real linux box. No dice..

My last resort would be a windows binary (I have no ability to compile on windows, though).

I'm thinking though one of the attempts at getting openpgp to work broke it.. which is kind of ironic as the openpgp part now works perfectly..

Edit: I'm pretty sure I know what's happened.. I'll start a new thread as it's getting offtopic.
