I have strange problem.

I use Yubikey 5 with OATH and gpg key applications configured on it.

In general it works (i.e. I got oath codes and can use gpg to
encrypt/decrypt messages.)
But when this key is in usb port it "gold circle" lights withut any
visible reason.

How can I debug communication with this key?
I tried something like:

find /dev/ -mmin -10 |grep -v '^/dev/pts'|grep -v -x '/dev/'|xargs -d '\n' inotifywait -m -r --format '%T %w <%f> %e' --timefmt '%Y%m%d %H%M%S' /dev/hidraw2
(after putting yubikey into usb port) but without success

Any ideas?
KJ
