Today I was using master (75861b6) and at first everything worked normally.
Then it stopped working. I'm not sure what I did at the time the error is in 
the log. I might have started a Windows VM in VirtualBox. But shutting it down 
did not help with the error. And starting it again after the error was 
resolved also did not cause it again.

The error in the log is:

2016-02-26 11:40:52 scdaemon[3727] DBG: ccid-driver: usb_bulk_write error: 
LIBUSB_ERROR_NO_DEVICE
2016-02-26 11:40:52 scdaemon[3727] updating reader 0 (-1) status: 0x0007-
>0x0000 (1->1)
2016-02-26 11:40:52 scdaemon[3727] sending signal 12 to client 3410


I have not removed the smartcard or the reader at that point. There might be 
something wrong with my cable though. I see a disconnect with immediate 
reconnect in dmesg log.

Sometime later I wanted to use the card for auth and the error is then:

2016-02-26 12:37:50 scdaemon[3727] DBG: ccid-driver: usb_claim_interface 
failed: -6
2016-02-26 12:37:50 scdaemon[3727] DBG: chan_5 -> ERR 100663404 Card error 
<SCD>
2016-02-26 12:37:51 scdaemon[3727] DBG: chan_5 <- SERIALNO

I'm sending you the full log of todays scdaemon session off list.
This time just restarting gpg-agent (and so scdaemon) fixed the problem which 
it did not the first time I've had this problem.

Regards,
Andre
