I'm getting a flash every 3 seconds with my Yubikey4.

Thinks seem to work fine though. U2F/OTP work on the demo page.

Code:
gpg --card-status
works, and after running this the light turns on solid, but instead flashes off quickly every 3 seconds.

Disabling CCID stops this from happening.

In the logs for pcscd I see:

Code:

A
Code:
pcsc_scan
runs until identifying the card, then hangs.

Code:
piv-tool --serial
worked yesterday, but now returns:

Code:
Using reader with a card: Yubico Yubikey 4 OTP+U2F+CCID 00 00
sc_card_ctl(*, SC_CARDCTL_GET_SERIALNR, *) failed -1201


I've tried resetting both PIV and openpgp. With the yubico-piv-tool I did a generate/selfsign-certificate/import-certificate and it all worked.

Other ideas?
