[Pcsclite-muscle] pcsc_scan suddenly does not find reader

[Johannes Kapune]

Hi to all,

my reader (cyberJack) normally works fine for me, except in some 
situations it gives no respond.

First I thought there is some problem with energy saving but it must be 
an other reason.

In logs you can see that directly before I use my online-banking-program 
I test with pcsc_scan and I get a good reaction. Than I tried to use my 
online program what fails, and after this pcsc_scan gives no answer.

If I unplug the reader from USB and reconnect I can use it again.


I'm on opensuse 13.1.      (systemd)

What can be the reason?
Where I can get more information / debug to find out?
What can I do to get back the reader without disconnect / connect 
(because of do not want to climb under work desk to do this)?


Best regards

Johannes
