    Logitech G19 interfering with other hardware?


    So I just discovered yesterday that my Logitech G19 keyboard is the reason I have not been able to use my external hard drive/USB drives/my iPhone 6 for the past few months.

    Whenever this keyboard is plugged in, it makes all of those other devices become "unrecognized" -- this is strange because other devices work just fine, such as my mouse/printer.

    Anyone have the slightest clue why this keyboard would be doing this?

    If this keyboard uses the dreaded "unifying remote receiver" then it is a known situation for which I have not seen any easy answer. I have a Logitech combo keyboard/touchpad using this USB receiver, and a PC which will not boot with the receiver plugged in. Check the Logitech product forums for the complaints.

    It is a wired keyboard. Have you updated the drivers for this keyboard through Logitech ?
    http://support.logitech.com/en_us/pr...ard-for-gaming
    Any other PC to try this on ?
    I see 6 USB 2.0/1.1 ports on this motherboard, have you tried other ports ? I not sure how you are connecting iphone, but other USB devices have you tried other ports ? Check the Device manager any yellow exclamation points showing with the devices plugged in ?Also check Universal Serial Bus Controller in the Device Manager. Look under Human Interface Devices and Keyboard for Logitech drivers.

    Yeah I have the latest version of drivers... However, I forgot to mention I'm running a pretty old mobo (ASUS P5Q3 Deluxe) and I've been suspecting the mobo for a loooong time until I recently found out this only occurs with the keyboard plugged in...

    I have tried all of the ports on the computer, and I also have tried another computer -- same issue, whenever this keyboard is plugged in iPhone/external HDD's don't work.

    Device manager isn't showing any yellow, however, when I plug in the iPhone with this keyboard in, it fails to recognize it and says "Device descriptor failed" -- As mentioned before, I spent months thinking something was wrong with the USB hub or iPhone and attempting everything to fix it, even manually installing Apple drivers.

    By the way, I just recently dumped my old G19 and purchased a new one thinking maybe it was just the old keyboard, still the same issue!!! This is driving me insane.

    I was looking at your motherboard on ASUS's site i see no updated system drivers for Windows 10 and assume the latest Windows 8.1 should be fine, if there were any windows update would check and download them. Thinking this can be a driver issue either with keyboard drivers or conflicting with system drivers, i am not positive.

    When you plugged in iphone or USB External device in Device manager it was a yellow triangle next to this device, did you right click and open the properties of that device in question, was it a code 43 ? In device manager when this occurs right click the device and scan for hardware changes. Some is shown here about similar issue if code 43. https://technet.microsoft.com/en-us/...=ws.10%29.aspx

    In some cases i would uninstall the devices from the Device Manager and reboot letting it reinstall those devices again. In Universal Serial Bus Controllers uninstall each USB Hub, USB Mass Storage and USB Root Hub and reboot.

    Open the Keyboard in Device Manager and uninstall and reboot and any USB root under Human Interface Device.
    Just start off with uninstall of the ones in Universal Serial Bus Controllers and see how this works.

    How long has this been going on with this keyboard and other devices, just since you tried an external device thinking that was always the issue ? How long since the upgrade to Windows 10 ? Other member may be right about contacting Logitech if you can about this, this issue might of always been there regardless of operating system for some. I am not sure about using these apple drivers on microsoft windows system just for USB

    This issue started happening shortly after Windows 10 install -- I did try all of the steps above, simply put: the iPhone/external hard drive(s) give a "device descriptor failed" error when connected while this keyboard is also connected.

    At this point I have started a support ticket with Logitech, but from the looks of it, they are gonna blame everything else but themselves.

    As sad as it may be, I'm currently disconnecting the keyboard and connecting my iPhone every time I need to sync, then I'm remoting into my main PC from another computer to use the keyboard/mouse while they are disconnected.

    How about other USB devices same errors codes with keyboard connected ? Must be then an issue with this keyboard and Windows 10, but what was OS of the other PC you tried it on with the same results ? Can try as mentioned uninstalling and reinstalling in Universal Serial Bus Controllers. Not sure how Logitech Support is, but i do know there drivers have been buggy for a long time, i have 2 Logitech devices and tend not to use there drivers, K800 Keyboard and M570 Trackball both which are wireless and i do not need the drivers for it to work. Not using the software drivers you will loose settings and changes in settings.

    You have tried the keyboard without the software drivers ?

    Correct, and still experiencing the same exact issue.

    It's weird because this keyboard has a screen on it, and it is powered by an AC adapter -- even unplugging that and letting this keyboard just function as a keyboard still causes the issue.
