use_get_string_simple anymore. * g10.c (list_config): New config option ccid-reader-id. (gpgconf_list): Add "reader-port". * apdu.c (open_ccid_reader): New arg PORTSTR. Pass it to ccid_open_reader. (apdu_open_reader): Pass portstr to open_ccid_reader. * ccid-driver.c (ccid_get_reader_list): New. (ccid_open_reader): Changed API to take a string for the reader. Removed al the cruft for the libusb development vesion which seems not to be maintained anymore and there are no packages anyway. The stable library works just fine. (struct ccid_reader_id_s): Deleted and replaced everywhere by a simple string. (usb_get_string_simple): Removed. (bulk_in): Do valgrind hack here and not just everywhere.

/* CCID (ChipCardInterfaceDevices) is a specification for accessing

smartcard via a reader connected to the USB.

This is a limited driver allowing to use some CCID drivers directly

without any other specila drivers. This is a fallback driver to be
|

used when nothing else works or the system should be kept minimal
|

for security reasons. It makes use of the libusb library to gain

portable access to USB.

This driver has been tested with the SCM SCR335 and SPR532
|
||
smartcard readers and requires that a reader implements the TPDU

level exchange and does fully automatic initialization.
