IIRC resp[6], resp[7] and resp[9] was mentioned. Does any one know what those values should be?

 
here is the offending line of code:
if(
resp[6] == 0x0 && (resp[7]&0xf) == 0x5 && resp[9] == 0x05) // PBA31307 confirmed
And it is in this file http://svn.gumstix.com/gumstix-buildroot/trunk/package/bluez/bluez-utils-hciattach-pba31308.patch
