Yubikey 4 stuck in CCID mode #600
Comments
Can you try running |
Here is the output:

Where does this YubiKey come from? Based on the diagnostics output, it doesn't look like a standard (sold to end-users) device, but it could be a custom configuration, which is something that can be done for large batches of devices for specific deployments. Did any of the applications you expect to work (PIV, OpenPGP, etc) work previously on this key? You should still be able to get it "un-stuck", but there is a problem in ykman where it is now failing to read the current mode. We'll fix this for the next version, but in the meantime the following command should put it back into
|
Yes, it used to work with AUTO mode and this happened only after I turned on the CCID interface P.S. thanks for the command, I'll try to return to OTP mode later |
I'm not sure what you mean by "AUTO mode", but I have done some more investigation and can conclude that this is indeed a non-standard YubiKey which only supports the (Yubico) OTP application. |
Sorry, autocorrect, i mean "OTP mode" |
Steps to reproduce
set yubikey mode using ykman to CCID
Expected result
Work PIV, OpenPGP, etc
Actual results and logs
it is impossible to use the key and change the operating mode
