I have encountered the same issue with my NAND-X that many other users in this thread have. I have attempted to dump and write the NAND on 12 different consoles (jasper, falcon and zephyr) that have the original QSBs still installed, all with no result. NAND-X seems to have no problem upgrading/downgrading to the V2 or V3 firmware, and will program my coolrunners just fine (on V2 i get "Cannot detect flash controller" and on V3 I get "Looking for USB Device: Can not continue"). With the V3 firmware installed, I get the ARM version error on Nandpro20b, which made me think that the computer was still communicating with the NAND-X properly...
I have already determined that it is most likely a faulty device, and have contacted the seller for a replacement (NAND-X is only about a week old).

"I recently purchased a NAND-X from you guys, and it has stopped working. The device will still power on, install, and even update properly, however, it will no longer read/write any NANDs for me. Every time I attempt to do so, I am shown the "Looking for USB Device: Cannot Continue" error.
I have done about 12 of these nandx qsb/coolrunner installs so far, and all of the consoles which I was able to dump the NAND on before are no longer working with my NAND-X. The same QSBs which were used for the initial install are still there (which worked great with the NAND-X the first time I dumped it) are no longer working with the NAND-X (I have checked all points and it is not a soldering issue on the QSBs).
I have done lots of forum searching, re-installed the drivers multiple times (on multiple different computers, both Windows 7 and XP) all to no avail. I believe the part which I have received is now defective, and would like a replacement.
I did want to say, however, that my experience with your company has been nothing but pleasant and satisfying. Your customer service/support has answered my questions in a timely and complete manner, and you have shipped every single one of my orders within less than 24 hours of purchasing! I really appreciate the awesome service of your company, and look forward to doing more business with you guys in the future."
