00005086 ccid_usb.c:588:OpenUSBByName() Can't claim interface 4/3: -6

-6 is LIBUSB_ERROR_BUSY

Your device CCID interface is already used by another program. You have to stop this other program first.

Bug was on the user configuration.

LudovicRousseau added a commit that referenced this issue Nov 13, 2015
@LudovicRousseau
CreateChannelByNameOrChannel(): call FreeChannel() in case of error
522ebb2 
If the creation of a channel fails then call FreeChannel() instead of
IFDHCloseChannel().
The ressources are unalocated but with no access at the lower layer.

Since the creation failed the channel is not correctly created and
only part of the reader stucture is initialised.

The problem was discovered with the folowing problem:
Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7ffff6fe2700 (LWP 6120)]
0x00007ffff5dca8f2 in CmdPowerOff (reader_index=0) at commands.c:1076
1076		cmd[6] = (*ccid_descriptor->pbSeq)++;
(gdb) print ccid_descriptor
$1 = (_ccid_descriptor *) 0x7ffff5fe0468 <usbDevice+40>
(gdb) print ccid_descriptor->pbSeq
$2 = (unsigned char *) 0x0

The pbSeq pointer is NULL and can't be dereferenced.

Its possibly be pn533 which blocks the access to reader for pcscd.

what I done was

  1. check if pn533 is loaded by :
    lsmod | grep pn533

if your output is like :

pn533                  40960  0 
nfc                   102400  1 pn533
  1. If output is similar to above then unload pn533 from kernel :

sudo modprobe -r pn533 pn533

  1. Now start your pcscd and then start pcsc_scan , it should now show your card status.
