mspdebug msp430g2553

Hi,
     I have  mspdebug --version
MSPDebug version 0.22 - debugging tool for MSP430 MCUs

1.   After running a few program loads into the chip (prog main.elf) I 
eventually get locked out.  In fact lsusb hangs til I remove the 
spy-wire.  I fixed the problem by replacing the chip on the TI exp430g2 
pcb.  After reprogramming the chip about thrice it has failed again with 
the same symptoms.  I've run out of spare chips any ideas on restoring 
whatever I've damaged?  I find it hard to swallow that TI parts are 
failing and suspect that I'm damaging some boot software in the chip if 
that's possible.  Any suggestions? Ian.
