yubikey 5c ykman opengpg commands fail

[KlavsKlavsen]

• YubiKey Manager (ykman) version: 4.0.0~a1-4 and 4.0.8
• How was it installed?: 4.0.0 with apt install on ubuntu 21.10 and then I tried pip install -U yubikey-manager
• Operating system and version: Ubuntu 21.10
• YubiKey model and version:5C nano firmware 5.1.2
• Bug description summary:
  When I run any ykman opengpg command I get this:

$ ykman openpgp info
Error: No YubiKey found with the given interface(s)
$ ykman openpgp keys set-touch aut on
Error: No YubiKey found with the given interface(s)
$ ykman info
Device type: YubiKey 5C Nano
Serial number: 10124802
Firmware version: 5.1.2
Form factor: Nano (USB-C)
Enabled USB interfaces: OTP, FIDO, CCID

Applications
FIDO2           Enabled      
OTP             Enabled      
FIDO U2F        Enabled      
OATH            Enabled      
YubiHSM Auth    Not available
OpenPGP         Enabled      
PIV             Enabled

Steps to reproduce

I setup my 5C and moved keytocard using gpg - and key works fine - but I cannot enable touch which is a huge security problem :(

Can you (with the YubiKey inserted) run ykman --diagnose and paste the output here?

Same issue. Used gpg --card-edit and that is working, but cannot set anything with ykman openpgp -> Error: No YubiKey found with the given interface(s)

I had similar issues until i removed a longer (3m) cable between key and usb-port.
Some functionality still worked with the cable in place, but using ykman didn't. Could be my hub or that specific port, too - i didn't test, but can do if it helps.

[KlavsKlavsen]

My key is directly inserted in my thinkpad laptop

[untbu]

I had the same issue on a raspberry pi 4. Changing the connection mode to ccid only (ykman config mode ccid) solved it.

[KlavsKlavsen]

That solved it for me too. Thank you @untbu
