I just got a Lexar Professional 128 GB 400x SDXC (class 10) and my Macbook Pro cannot format or read it with the built-in reader.  The reader is model 0x16bc (not a USB device).  Everything I have found indicates it should be compatible.  The OS is 10.6.8 (10K549).


It's not a connection issue; it sees the card but reading / formatting always returns an error message.  It can use smaller (non XC) SD cards fine.


I can read/write the card through a $6 Transcend card reader, but 128 GB at USB2.0 speeds is pretty useless.


Is there something wrong with the early SDXC readers?
