USB ports keep disconnecting and reconnecting.

Ever since I completed building my computer several weeks ago, I have noticed I run into problems with the usb ports in the rear of the computer. Anything plugged in will seemingly randomly disconnect, then reconnect seconds later. The problem is the frequency of this; the disconnects can occur every several minutes, and sometimes in rapid succession.
I am fairly certain that I have all the proper drivers installed, but then again, I'm by no means tech savvy.
I've had no problem with USB ports that are on top of my case, but unfortunately that only limits me to two ports without usb hubs. I've currently got my mouse and keyboard plugged into those, along with one hub for expansion. Meanwhile, my external drives are rendered useless.

1. I've also looked up solutions and have tried unchecking "Allow the computer to turn off this device to save power" under system options, but this does not solve the problem.

    I did all of this, it worked for a couple days and then windows started to disconnect and reconnect again. I've checked and double checked to make sure it stayed disabled so i'm baffled as to what is going on. I cannot format or transfer files without it getting disconnected and reconnected. Please help.
  4. This solution that I found worked perfectly for me:
    When booting your PC, enter the BIOS setup and disable USB 3.0 support.
    There will be no more USB 3.0, but at least USB devices will not disconnect anynore.

    You just saved my day.
    That was it, and being a WP developer it was driving me crazy !
  6. I have a similar problem on my Asus Z97-A motherboard, but I have been able to narrow down the problem. Read on for something interesting...

    1) For me, the problem is only with SOME USB 3.0 devices like Card readers and external harddrives (some multidtrive USB 3.0 readers do work, some HDs are temperamental about when they will work) - this is all very weird.
    2) But the most weird thing is that the problem only occurs when I join my windows 8.1 pro pc to a domain, as soon as I take it off the domain, the problem goes away - this seems to imply that the domain group policies have something to do with it. But why then do some drives work on and off?


    I tried the power options as described in the post (http://www.tomshardware.com/answers/id-2335635/usb-drives-disconnected-reconnected-usb-work-great-usb.html)
    and I have tried disabling XHCI as described in the post (http://www.tomshardware.com/answers/id-1885037/windows-usb-devices-disconnect-reconnect-power-saving.html)

    None of the above worked.
  7. I've had the same issue for a little while now. Also with a USB 3.0 port. Just one, in fact, and only in combination with one certain HDD. I haven't tried out above steps as I'm in the middle of a clean install. Let's see if that changes things.

    PS I love how this thread is over a year old and still going strong.
  8. I have a similar issue, except mine doesn't d/c randomly and every few minutes, then r/c 2 seconds later, it is literally a perpetual loop of d/c and r/c. The constant ba-ding, ba-dong, ba-ding, ba-dong , is incredibly annoying to say the least.
    This happens on any computer I use, with any cable I use, and I have wiped the phone.
    I did root it and this started after an update before I rooted it (Ice Cream sandwich I believe).
    The issue exists within the software on the android device. I have posted incredibly detailed steps in other forums and threads throughout the internet, none has any resolution for the issue. Persisting since roughly 2012 i believe?
    Don't expect a resolution, ever..
    My Solution?, Bought an Anker universal battery charger. bought an extra Li battery for my phone and always have a second charged/charging. When it dies I can swap out.
    Note: from time to time the phone will connect and charge as desired.

    I ended up doing the opposite and it seems to work, as it was already disabled.
  10. i have the same problem on WIN7 with my Asus k73 boarded laptop, odd thing is it is happening to my USB MIDI controllers... and what is even more odd is that the laptop does not have USB 3.0 ports or the option in the bios obvies. tired adjusting the power options hope that works.
  11. okey i have a solution for desktops and not for laptops since you will open your motherboard. looking at your mother board you will find some wires and it is named usb 5, usb 6 and so on the motherboard the same as this. http://i.ytimg.com/vi/aE2y30bIejE/maxresdefault.jpg. as you can see there is another socket that can be connected. if your usb wires are connected at usb5 then switch it to usb 6. or just switch it to the other.

    I have tried this and it worked because looking at other solutions doesnt solved it except this method. maybe its faulty wires or something. its just a suggestion because it worked for me. hope this helps.

  13. FIXED bend the little tabs on the ports in so they grab on the the indents on the usb plug these tabs can bend slightly causing the usb device to disconnect when moved slightly

    You are the MAN! This was exactly my problem on my Asus laptop. It was doing it with any usb device (mp3 player, android samsung phone, or anything). And I can feel that it was related to a connection/movement issue - even though I wasn't moving anything. It would have its good days and bad days. The slightest movement would send it to a connect disconnect loop, and then it was just endless that I can't do what I need to do with the device!

    Thanks for the help and good luck to everyone else.

    I have tried this yet my Nexus 4 keeps reconnecting and disconnecting from my laptop. I have tried updating drivers but it says they are up to date. What do I do to solve this problem. Also do I have to disable On Battery and Plugged in or just one of them. If so which one? I've disabled BOTH of the options available yet it doesn't seem to work. Might just have a faulty cable or something

    Are you having that endless connect/disconnect loop? If so, it might be hardware related and not software. This is likely caused because your laptop literally thinks you are connecting and disconnecting the device that fast and that many times. Since you're obviously not intentionally doing it, then it's probably because your usb cable is losing contact with the usb port on the laptop. Have you tried another usb port on the laptop and another usb cable? If it's not the cable, then have you tried what robtapp mentioned about bending the little tabs in the usb ports on your laptop? Good luck
  17. My laptop is doing this even without any devices plugged in to the USB ports :/

    Same problem with WIN 8.1 and WIN 10... All drivers updated, tried factory reset and so forth..
  18. So I'm having similar problems, using my laptop (Lenovo S21e). I've used the suggestions from above and nothing seems to be working, but going with the bending of the USB drive, I don't know exactly how to do that. Any suggestions?
  19. JJx: I was having the exact same problem as you, and the solution for me turned out to my USB network adaptor, weirdly enough. More details on that in this thread: http://answers.microsoft.com/en-us/windows/forum/windows_8-hardware/a-timeout-occurred-while-waiting-for-the-ehci-host/dbb475c6-f048-4c57-b147-068cd7439ecf

    Next time it happens, or if you remember the approximate date/time it happened, check your event viewer for errors around that date/time. Check the very first log during the time that it happened--for example, in my case, my error occurred at ~9:43PM. My event log had a skip from 7PM to 9:39PM, so I checked the 9:39PM entry. Under the "general" tab of the Event's "Event Properties" window, check the text box description--it might give you some insight. If not, just paste the description into google (like I did), and I can almost guarantee someone else will have had this issue.

    Good luck to everyone else with this problem!
  20. I was having this problem on my desktop but it was more than just USB devices. My dvd burner didn't read, one hard drive vanished and the computer would crash, but the first thing I noticed was the USE devices d/c and r/c.. I figured out it was my PSU and replaced it with a 750 watt Antec and no issues since. But it's only been a few days. My old wacom tablet quits working and I have to log out and back in to fix that, but I've had that problem since I bought it 3 computers ago.
  21. Found the solution. I had that same problem. It was temporarily fixed by Windows 8.1 patch KB2911106 but the problem started again after the Windows 8.1 update 1. In my case I have a 2TB seagate external expansion drive. I just redid the same thing after Windows 10 and it worked again.

    The fix can be found in the link
    http://www.registryrecycler.com/blog/2013/12/how-to-fix...

    It requires you to update your register, carefully follow the instructions that are well explained. It works.
  22. KJK1908 has the answer.
  23. i tried everything but nothing helpes. microsoft thinks they have the cure.. here is the link

    https://support.microsoft.com/en-us/kb/2416007

    BUT id doesnt work a bit... after i install the hotfix nothing changed.. They described the problem very well but the solution is useless
  24. I had same problem and nothing will solve it.

    Then I found this solution- using this hub did (no need for external power connection), just connect the hub to your PC USB exit and the phone to the hub.

    That's the hub I used http://www.ebay.com/itm/Powered-4-Port-USB-3-0-Hub-5Gbps-Portable-Compact-for-PC-Mac-Laptop-Desktop-/141512041114

    Good luck
  25. HI all,

    Had the same issue but now its working fine, please use the below steps :
    1- Open device Manager.
    2- Human interface Devices. ( you will find many options such as micrsoft hardware USB, USB input device)
    3- Right click in one of them or double click.
    4- go to power management.
    5- Uncheck the option of " Allow the computer to turn off this device to save power" than OK.
    Note* try to use step #3-5 on all available option*

    Try to do the same thing in Universal Serial Bus controller.

    Thank you so much! This straight up worked. I thought I had a faulty motherboard, I was about to file a complaint to Newegg.

  28. HI!

    See my solution at the end of this message.

    I used to write Android applications and to test them on my phone connected with a cable on USB port of my PC.
    And everything works fine.
    But, my PC died recently.
    So, I decide to buy a Surface Pro 4.
    Now, I have a Surface Pro 4 with Windows 10.
    I still want to write Android applications with Android Studio.
    I install Android Studio and follow all the instructions on Google site.
    When my application is completed, I want to test it on my my phone as usual.
    But, the Surface Pro 4 never recognizes my actual phone and any others phones and tablets I have.

    I tried all the solutions on this forum.
    Nothing works.

    Is the problem caused by

    As a last resort, I change the cable between the Surface Pro 4 and the phone.
    And everything works fine now.
    Wow!


    And this cable was in the box of one of my phones.

    So, do not forget to try to change your cable.

    Bonne journée!

  31. I've had this problem over and over as a developer using mainly desktop pc's. In every case it was to do with USB 3. The workaround was always to disable USB 3 support in BIOS and / or uninstall USB 3 drivers and allow USB 2 drivers to be installed in their place. Not really a solution but I'd rather lose USB 3 than have to put up with intermittent connection which can affect everything on the bus.

    Cleanup with
    http://www.softpedia.com/get/System/System-Info/GhostBuster.shtml
    to remove any ghosts.

    Monitor with
    http://www.majorgeeks.com/files/details/device_remover_543c.html
    to hunt down any remaining problems on the bus.

    Thanks a lot mate worked like a charm, had this problem ever since i upgraded. external drive switched back within seconds of the settings being changed. your a star :)
  33. As mentioned, Selective Suspend it typically the cause of this issue. However, using the control panel to disable the feature doesn't often work. We've found the surefire method is to use regedit. Start, Run, regedit <enter>. CTRL+F, enhancedpowermanagement <enter>. Change found keys to 0 (zero). (F3 to search for next key after changing the first, until it can't find any more). There will be one or two that can not be changed, ignore those. After changing all found keys, reboot.

    There is something about electrostatic interference with computers... I noticed when my wife would Turn on the burner to the stove my USB sound would go off. With a recent computer build it would do it when you turned the fan on and off. I GUESS it has something to do with electrical spark. Some motherboards have an option to reduce this, some dont... OR you might have a lose USB connection to a wireless Xbox controller, but I'm pretty sure its the first one. Hope that helps! ;) oh and there should be an option to "show all options" when looking to selectivity suspend usb devices.
  36. I'm having a similar issue with the Gigabyte F2A88XN-Wifi mobo. If it's a 2.0 USB drive the PC won't boot, and when I remove the drive and boot, when I put the 2.0 USB device in I get a regular but random stream of d/c and r/c. When I use my 3.0 External Harddrive, no issues at all. Any ideas?

    Sorry, just realized I posted this as an answer, and I went to edit it, but don't see how to change it. Sorry guys.

    :/
  37. I had the same problem and I couldn't find any solution online anywhere- apparently it is a hardware issue from the devices getting a power overload so they shut off. However, I have discovered that when I use a slower cable/ older cable, the rate at which my devices disconnect is substantially reduced. For example, for my Samsung phone when I use the cable that came with the phone (which has fast charging enabled) it rapidly disconnects and reconnects, but when I use a basic android usb cable it's fine. Hope this helps!

    I have been having the same problems, i found that using This method and also turning off auto sleep on the phone works a treat, apparently the phone screen shutting off whilst connected to the pc has a negative affect where as making the USB connection disconect.
  39. I found solution for disconnecting and reconnecting of my game controller (Saitek Quadrant) in Registry.
    To prevent constant disconnecting and reconnecting you need to set parameter EnhancedPowerManagementEnabled for your USB device to "0".
    This parameter is locates here - HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB
