RFID reader/writer + Pepperl & Fuchs transponder

I have bought the RFID reader/writer module 28440 and have been trying to read data from Pepperl & Fuchs IPC03-54-T8 transponders (link).
I have found information that these transponders are based on EM4450, so it should be possible to read/write those with the 28440.
However... the only answer I get from the 28440 is ERR_LIW (status byte = 2).
One thing I came to think of is that maybe the P&F transponders are password protected from factory to enable only P&F readers/writers to use them.
Does anyone have any experience with this, or with similar applications/issues?
I found this in the EM4450 manual:
When a word is read protected, the output will consist of 45 bits set to logic "0". The password has to be used to output correctly a read protected memory area.
This indicates that my problem might not be password related since I get nothing in return at all. On the other hand, I have no idea how the microcontroller on the 28440 board handles a problem such as that?
Added a bit later
This post kind of indicates this issue has been solved by getting a new 28440. Has anyone else had problems with faulty items?

It turned out to be power related. I had simply soldered a FTDI USB-Serial cable to the 28440, and powered it through USB.
When I powered it from my lab supply it worked great. Might be of interest for others here!
HOW DO I MARK THIS THREAD SOLVED?
