You could eaasily verify that by pluging a LPT cable which wouldn't work either in your case..... My case is different than yours...
Maybe UbergeeK could inform us if they had made any board modifications,,, in NandX the last year as believe it or not I would like to buy another one.. LPYT is slow...
If instead of coming here to make chaos and blame the equipment that is just brilliant, I used the flux for good, done well for checking welds on well with the image of the exact points with the exact colors of the cable of the NAND-X, hours would have extracted the NAND without problems, even as others I do JTAG as a service, just this week 12 console between slim and phat, for over a year I have made very many, and very often goes out the mistake, the first thing, am referring 1 for 1 welds as best I can do, and then fail "Sbam" read perfectly!.
When you attack the NAND-X USB is detected it? So, 2 +2 is 4 because everywhere is the man not the machine, it's you that differ from all others, the NAND-X is the same for all 100,000 copies sold!
Here we help "free" even people who have bought products such as NAND-X and uses the LPT, is not the case venirsela to take with these people, as with Modtraders, but also they are very accurate and honest, and if they I hope you have contacted them to contacts or you will be more accommodating, and do more tests first, believe me! If then the NAND-X OK you're back where you are now, but if you try to redo all for good 1-2-3 times you've become even better at doing JTAG.
