If the user specifically requests the driver, throw an error if it
cannot find libnfc-nci.
Also use the value from pkg-config to determine the library name,
instead of hard-coding it.
1. Modify pcsc.c code, add R502 and bR500 support into PCSC driver
2. Update readme, tell user how to build with pcsc driver
3. Add FAQ for bR500 and R502 in readme
Adding pn71xx NXP's NFC Controllers through Linux Libnfc-nci
(note I have only tested this does not break build etc. as I do not have a reader with this chipset)
- only initiator mode is supported
- properties are choosen as they are available via PC/SC, the rest of
the defaults are chosen to be compatible with Mifare DESFire
- This commit allows reading Mifare DESFire via PC/SC with libfreefare
Adding support for extended Magic cards:
- DirectWrite cards
- One Time Write cards
Direct Write cards support modification of B0 directly, without any unlock codes. When we are attempting to detect if a card is 'magic', we will attempt to modify B0 directly as an initial check.
One Time Write cards support modification of B0 directly, one time only. They do not respond to magic commands, but have a fixed UID coming out of the factory. We now detect this UID, and if so, deem the card 'magic'.
Adding support for "DirectWrite" Ultralight tags.
- The latest generation of "Magic" Ultralight tags support DirectWrite to B0.
- Several versions of these cards are bricked if the older 'unlock' command is issued to the card.
- To avoid this, when detecting if a card is magic, we attempt to modify B0 directly. If this fails, we proceed with an unlock command.
stdint.h is needed for uintX_t typedefs which are
used to replace u_intX_t in libusb API headers in the cmake files

PN533 easily corrupts its USB descriptors. We know that and we
already try to detect and even repair them.
However there are situations where lower software layers get
confused before libnfc can help. On Windows, libusb may set
dev->config to NULL, but we can also have a non NULL dev->config
referencing corrupted data.
In order to get more robust, let us replace the Windows libusb
specific (dev->config == NULL) test by an inconditionnal use of
hardcoded descriptors when they are available.
