I was going to get a breakout bard- a small unit that looks like a "gender changer" with with LEDs s to error check signals - instead I just just swapped computers and the problem I had was too low voltage on the laptop!
Are you on a laptop - some only drive at 3.3 volts and if you need 5 - well, there you go,

Experience is the BEST Teacher. Is that why it usually arrives in a shower of sparks, flash of light, loud bang, a cloud of smoke, AND -- a BILL to pay? You usually get it -- just after you need it.
