Hi,

When I'm removing an USB CCID smartcard reader, I have to restart pcscd in order to use ANY attached reader again.

This is the pcscd log when plugging the reader in:

This is the pcscd log when unplugging the reader:

Feb 9 15:40:16 localhost pcscd: ccid_usb.c:419:WriteUSB usb_bulk_write(001/004): No such device
 
This is my configuration:
 Debian unstable
 kernel 2.6.8-2
 pcscd 1.2.9-beta6
 ccid 0.9.2
 
I tested it with the ACS 38 and the SCM SCR 3310 CCID readers.

This does not occur on another debian unstable system with the same pcscd/ccid versions.

The only difference is that udev is running on my system. Could this be the problem ?

Best regards,

Serge
