What I do is to "kill" the com.apple.ifdreader process.
I used to send the KILL (-9) signal but a HUP signal works as well and
gives a change to the process to exit cleanly.
Note that any connection to the reader(s) will be lost.

The com.apple.ifdreader process is automatically restarted when a new USB
reader is connected.

Maybe there is an official (cleaner) way to do that but I do not know it.

10.10 is the same as 10.11 on this point.
On 10.x with x < 10 you can kill the pcscd process.

You should not have to reboot a Unix system :-)

Bye
