Makes sense, because the latest firmware version has a watchdog enabled 
which older firmware versions don't support - this means if you use DFU 
to update the firmware, you don't update the boot loader to he previous 
version as needed. This probably results in a device that is constantly 
resetting.
Best way forward is to use the at91flash approach and to flash a 
samba-imgage (concatenation of DFU+main firmware) at least once.

It also could be that the current SVN firmware version is broken. Please 
try:

- release 1999 of https://svn.gnumonks.org/trunk/librfid
- release 314  of http://svn.openpcd.org/trunk/firmware

these are the known-good versions shipped and verified to work.

Attached you'll find the compiled binary samba image of the reader 
firmware to make sure that the firmware image (16260 bytes) is right.

I used the following tool chain to compile the image:
