    I have been making a few mods to my phantom and the last ones were some new T-motor motors and Carbon fiber props. This needs a bit of tuning in the gain department and as I am still using the stock radio I can only do this via computer. Quite a few successful connections and then all of a sudden it failed to recognize the phantom.

    I did a google search for the issue and didn't find any solutions online other then send it back to DJI but there seem to be quite a few people that have had some USB issues. To me my issue at least seemed more like a software issue then a hardware fault so figured I would try and find a way around it, as the phantom was still displaying a solid green light when connected telling me it has found the PC just the PC hasn't recognized it. I tried manualy forcing the DJI driver on top of the one USB device that was unrecognized in device manager. This was obviously the Phantom as it went away when disconnecting but forcing the driver file didnt work here.

    I I also tried all the regular stuff such as different ports, uninstalling DJI Driver and Naza software. Rebooting and still no luck, then I though id try and completely eliminate all DJI software from the computer. I used revo uninstaller for this as I have used it in the past for software that's playing up.
    Here are the 3 programs used by the Phantom and NAZA as seen in revo uninstaller.

    I found that here DJI installed
    "DJI Driver version 1.0"
    "DJI NAZAM Assistant version 2.12"
    Both which I already tried regular uninstall/ re install with no help.

    I also noticed "Windows Driver Package -djiinnovations inc. (usbser)"
    This I though was the most likely culprit as even if I uninstalled the DJI driver and Naza this remained.

    So I decided to completely remove all DJI software using revo, here is how I uninstalled the last part but same process for all 3 programs.

    First right click on the program and select uninstall, a popup will come up saying "all programs using this driver will no longer work" select ok or yes.

    Once this is done do a full advanced scan

    Then make sure you press select all and delete to clear all remaining entries linked to this program.

    After you do this then repeat the process for the DJI driver, and you may as well do the same with Naza to make sure all is completely removed from your computer.

    Next go Back to the DJI site and install the driver and Naza software and if in my case you may be able to communicate with the NAZA again via your computer.

    Plain and simply USB is great when it works but a complete ***** when it doesnt, most of the connectivity is meant to be done automatically without any user interaction. So when you have a USB issue the best way to try and fix it is make sure you remove all traces of the hardware your trying to install along with any software like NAZA and try install it again.

    Also when installing the 64 bit driver on windows 7 you need to click ok to enable it to install the driver sfter the warning that publisher isn't identified.

    Then install NAZA and hopefully its all working for you, there are possible hardware faults through crashes and such so doing this wont help everyone but should help a few that are having a USB conflict issue. Also if you never managed to get NAZA to connect to your phantom you will need to work out those issues possibly make sure you have admin access to your login and disable UAC to see if that helps install the driver. This method will only help people that could connect but then lost the connection later on for some random reason and who's phantom is still showing a green light as soon as connected to your computer via USB.

    I had the same issue - made a maiden flight, updated the software, made a second flight of about 5 mins, then when I tried to reconnect to turn IOC on, my USB seemed dead. I did a full uninstall and reinstall, still no USB. I then installed the software on my older and bigger Sony lap top - still nothing. Installed programs on my HP desktop - still a dead USB. Vendor said send it back and a replacement arrived within 24 hours.
    Glad to hear your solution worked though.

    If its not working on multiple computers it seems like more of an issue then I had especially if you never installed the software on all the other computers. Once I found mine wasnt conneting to my pc I really hoped I didnt have to send it back asnIm sure changing motors voids warranty and I need access to Naza to help set everything up. Luckily in my case it wasnt a hardware issue and I suspect in some other cases this could also be case though as in your example there are times when it must be more then that.

    When your usb died and you connected the phantom to a computer did it display the green light or just stay as if its not connected. Ny guess is if the phantom changes its led to ansolid green indicating its in usb mode but pc isnt registering its just a software issue on the pc side. If the phantom is unchanged when connecting the usb then its likely more serious and can only be fixed by dji, seemsnmany companies are using very cheap low quality USB hardware these days as fail rates are a bit high. Software issues are also very common but its not always just a software issue.

    When I connected the Phantom, it appeared that it was not connected (the Phantom's LED display remain unchanged).

    I did the same thing you did, researched on the net and saw that a few people had a USB that had lost the connection inside, they opened the Phantom and simply reconnected the USB.

    After spending that amount of $ on what is basically a toy - I was not willing to risk opening the case, find that wasn't the problem, and then be told I had just voided the warranty and was stuck with a Phantom I could still fly, but never connect again. :shock:

    I've got an unrecognised device after a new motor install as well, with yellow blinking lights rather than green, when plugged in.

    Anyone know of a way to solve this?

    Soooo, I figured out my problem.

    Something damaged the USB cable that plugs into the Naza on my Phantom 2 Vision. I bought a new one and I was able to connect, although the lights are still flashing yellow.
