Have you tried a different cable? This is the kind of thing I've seen with
intermittent connections (cold solder joint, lead sitting on pad w/o
solder, a broken wire that makes contact as long as the cable sits just
so). Also are you using the appropriate power supply for your level
translator (not running a 5V chip on 3.3V)?
