[Pcsclite-muscle] pcscd Yubico Yubikey 4 U2F+CCID init failed

[Trevor Clark]

 Hi Dr. Rousseau,

As far as I can tell everything about the yubikey is working as
expected except the Daemon. I can see the card with pcsc_scan. I can
interact with the card through pk11 etc.

```
[tclark at tc-desktop ~]$ pcsc_scan
Using reader plug'n play mechanism
Scanning present readers...

Possibly identified card (using /usr/share/pcsc/smartcard_list.txt):

Thank you for taking the time to respond. I really appreciate it.
