In my various experiments with the openpgp stuff what I didn't realize was the yubico OTP is a javacard application - the documentation kind of implies it's a completely separate personality.
The ykneo-ccid-modeswitch tries to select an AID of A000000527200101 - that doesn't seem to exist (it must have originally, everything was working until a couple of days ago).

I don't suppose there's a cap file available to restore it the applet? Or is it a matter of sending it back (given the postage cost to the US I might as well buy a new one in that case).
