Drivers/Hardware :: USB Ports Being Deliberately Disconnected Or Disabled
Jan 19, 2016
I am being bugged by a problem associated with USB ports apparently being intermittently disabled or disconnected.
The result is a cacophony of device disconnected sounds being played. It ultimately means the PC has to be shutdown. Occasionally a device connected sound will be heard as well.
I have heard that Win 10 is disabling or disconnecting USB ports to save power for tablets and such. Understandable for limited power availability but for PCs where power is always available this seems misguided.
I need to know if this is by design or can it be selected off via registry option.

So I was messing with the services startup parameters and I managed to change something which is now preventing my USB ports from working. My kb/mouse lights up during boot and then goes off and stays off just before the login screen appears. How I could fix this without reinstalling windows again? I've tried all ports but none of them work .

I am getting numerous Device Disconnected sounds and occasionally Device Connected sounds.
I am trying to trace the source of these and started looking in the event logs.
There does not appear to be any events with Critical or Error tags showing.
Should the Device Disconnected event create a log entry?
If it does not can one be created to give me a clue as to what has been disconnected? Everything still appears to be working after a Device Disconnected sound is heard.

I have upgraded my OS to Windows 10 from 7 and I can not see the PORTS(COM and LTE) in the device manager. I tried everything but don't know how to find it.

I just put the 1511 upgrade on (for the third time, but that's another story). I've noticed that when I open File Explorer I have a WHOLE BUNCH of USB ports that have nothing plugged into them... What the upgrade did, but these weren't visible previously. How do I turn them off?
And yes, I've gone into the File explorer options in the control panel and UNCHECKED "Hide empty drives". Didn't appear to make any difference...

I very briefly switched on the IGP whilst swapping from Nvidia to AMD last month and now Windows Update is constantly trying to update (and failing) the drivers even though no Intel drivers are currently installed, I used DDU to remove the Intel and Nvidia drivers.
How to stop it? Now whenever I open Windows update I get updates are available for Graphics Adaptor WDDM1.1, 1.2 and 1.3 for Intel HD Graphics 4600
I can't even search for new updates any more!

I have a Sony Optiarc DVD drive. When I first upgraded from Windows 7 to Windows 10 it was working but later it is not. It shows in the Bios but not in Windows. I even bought a new Lite-on DVD drive and put it in and still not recognized by Windows 10.

In win7 and win8.1, i could set the screen of my tablet (Lenovo Miix3) to switch off after 3 min (not sleep, just switch off the screen). Tapping the touchscreen would bring it immediately to life again.
With win10, this does not happen. I need to click the on/off button to bring up the screen. So, it seems that Win10 switches off the touchscreen electronics. This is not a hardware issue, because previous Windows versions would let me switch off the touchscreen backlight but retain its sensitivity to touch (and therefore switching on upon tapping).
What do I need to do to restore the standard behavior (tappable touchscreen after switchoff) in Win10?

My touch screen randomly won't work, only to find that it's disabled in Device Manager. "USB Input Device" is what it shows up as. I believe it's a software I have installed that may be interfering.

Upgraded (???) a Windows 8 machine (HP with MS ergonomic keyboard) to Windows 10 a couple of months ago. It seemed to work, but most of the apps didn't work, and I couldn't access files as Administrator. this week I upgraded (???) a Lovono using Windows 7 to Windows 10. They are networked with printers and other computers via ethernet. Thursday afternoon the HP stopped recognizing key strokes. It allows password input on restart, but will not type anything else. It clicks like the buffer is full. Yesterday the Lovono started doing the same thing. My first thought was virus, although McAfee runs constantly on both machines. Used Malwarebytes on both and found a few PUPs, but no malware or virus. One forum suggested using DriverWizz, but it didn't change the keyboard driver. The Windows 7 computer on the same network, sharing files with both, is unaffected as yet. I'm thinking the solution will be to junk Windows 10 and go back to 7 and 8. If Windows 10 were a Vacuum Cleaner it would be terrific, but sucking like this is not all that terrific for an OpSys.

Since I upgrade to Windows 10 (coming from 8.1) in my friend's Dell Optiplex 3011 All-In-One computer, with built-in speakers, the audio has been disabled, and I see the Windows speaker icon is with an "x". In Windows 8.1, the audio was working normally, so it's not a hardware issue.
However, if I plug in an earphone, the audio output is enabled and the Windows speaker icon changes to normal one. I installed the latest version of Realtek HD Audio driver (R2.79), and restarted, but the audio continues disabled unless an earphone is connected.
I first upgraded to Windows 10 and installed the Realtek audio drivers. Then, I performed did a clean install and installed the Realtek audio driver again, but audio is still disabled. When I open the Realtek Audio Manager in Control Panel, only the microphone tab appears. When I plug an earphone, the speaker/earphone tab is visible as it should be, disappearing after I unplug it.
I reinstalled Windows 8.1 in his system hoping to have audio working again, but the problem persists. I've tried installing the Realtek HD Audio driver from Dell supporte page for my product (entering the service tag to be 100% sure), but no luck. Windows troubleshooting is useless as usual, only asking me to plug in an earphone, like I didn't know it. I even upgraded Dell BIOS/UEFI firmware to latest version (A07), but it didn't fix anything.
Info:
System: Dell Optiplex 3011 All-in-One
OS: Windows 10 Home Single Language
Realtek version: R.279

my Mouse, Keyboard and my audio interface get disabled a few times a day. at seemingly random intervals.
mouse and keyboard are mostly no problem because they reconnect instantly, with one exception today which forced me to restart as win10 refused to detect them again.
but most annoying is when it disconnects my audio interface because it never manages to reconnect without me manually pulling the usb plug out and in. some programs and game crashs when i do that, or just wouldnt play any sound without restarting the program in question.
i installed win10 a few weeks ago, its a clean install not an update. this problem hasnt occured ever before last week or something. so i suspect some auto-updates could have messed with it. i have not tinkered with usb drivers or anything like that,

I was working on my Qosmio x505 on my router as I have been for the past 5 years with no problems. This time the laptop randomly just disconnected from my WiFi and wouldn't reconnect! When I try to connect to the router it acts as if I have never once connected to it (asking me for the pass). Once I put the password it does its usual thing and then gives me the message that it cannot connect.
I should mention that my laptop connects to my Samsungs hotspot just fine. Also, all my other devices (2 in total) connect fine to my WiFi. I tried to disconnect them and then connect my laptop and it didn't work. I reinstalled the WiFi driver but it didn't work. I tried troubleshooting but when it asks me to look for available networks and I press the option it completely bypasses the step! I tried to restart the laptop and router, didn't work either. I got so desperate that I backed everything up on my external hard disk and did a total windows 10 reset. That didn't work either!
I am sure I am putting in the password correctly. Also, when I left-click on the WiFi it doesn't give me the option to "forget" the network.
Windows 10 has been working for me very well since it rolled out, I doubt that it is a problem with windows 10 but it may be.

After upgrading to Windows 10 I'm getting internet problems. Most pages are very slow to load, I often get connection timeouts and lag in some games, despite the ping not being really that high. I thought it could be a browser issue so tried other ones but it didn't work. I've already updated all the drivers, have the latest BIOS and deactivated the P2P sharing of Windows Updates in local connection and applied all the updates that came up with Windows Updates. Oddly enough, Steam downloads and voice chat don't present any problem.
I've already tried the connection troubleshooter, to no avail, and also tried to renew the IP using instructions in a Tom's article:
1. Press Windows Key + X and select “Command Prompt (admin)”.
2. Type ipconfig /release and hit Enter.
3. Then type ipconfig /renew and hit Enter.
4. Type Exit and hit Enter."
But when I applied the commands I got the following message: "no operation can be performed on ethernet while it has its media disconnected" I'm connected using an Ethernet cable.

I am running Windows 10 Home version 1511 build 10586.63 on a Dell XPS L502X laptop. I have just bought a Bose SLIII bluetooth speaker. I can connect it up to the laptop no problem and it works well, however when I disconnect it I cannot reconnect them without removing the device and pairing it again. On my Android phone it is detected and automatically reconnects. Why I have to recreate the device each time I want to connect on the PC? If I do a Win+A then 'connect' and select the speaker device, it tries for a few seconds then I get a yellow message 'Couldn't connect'. When I remove the device and 'Pair' it again it connects immediately.

I have a Lenovo IdeaPad S10-3, it was upgraded from Windows 7 Starter to Windows 10 early august. Working find everything until updating to version 1511 in november, after rebooting with the new version the WiFi appears disconnected, it only shows airplane mode and I can only connect to internet by cable. I have tried changing drivers, disconnecting and reconnecting wireless, even going back to former Windows 10 version, etc. but no way. WiFi appears with a red cross!. Why WiFi worked so fine in the former version and why it´s disconnected in the new version?.

I have an odd issue where a Samsung SSD that is no longer in my system is still showing. The weird thing is if I bring up the properties, and then populate the fields of the drive (by pressing the populate button), it shows the capacity of the newer drive which is double the size. This drive is not a Samsung drive though. So I'm not sure what's going on here - see picture where it clearly states (at the top) that I'm looking at the properties of a 250GB Samsung drive, but the populated fields show it to be a 480GB drive.

A client brought his desktop into us with the following issue:A few months back he upgraded to Windows 10 without any issues. A few days ago his mouse and keyboard stopped working (both are USB). He brought the machine into us and I took a look at it. I found that, and I thought this would resolve it, he had a bad hard drive and cloned it. I installed the new hard drive and the PC booted back into window with no issues except that I still don't have any working USB ports. The PC only has USB Ports, no PS/2 Ports. No matter what USB port I plug a mouse or keyboard into it does not register. I suspect it could be a driver issue, but I can't access the PC at all to check. I want to try and avoid doing a backup and reinstall of windows if possible.

After the windows 10 upgrade, usb ports are not working. System detects a device. I can see the device in device manager, but no icons are displayed in file explorer. I cannot open any of the external usb storage device or print from a printer connected via usb port.

I am trying to install a generic text printer onto a windows 10 tablet but when the printer is paired through Bluetooth the Com port it is using is way beyond the normal Com port numbers.
After the printer is paired I would normally add a local/networked printer and select the same port as the Bluetooth device, when this is in the range 1-4 that is fine, but (due to repeated attempts) it is now up at Com19
I have looked online and found articles for Windows7 talking about uninstalling the un-used Com ports (that windows thinks are being used) but I'm not sure how to reach the same areas in Windows 10
I have so far tried the following:
1. turning it off and on again
2. using device manager, view ports, under the view menu setting 'Show hidden devices' but I can only see the two latest ports (19/20)
3. I have looked at the properties of port 19 and tried to change the port number, but this is where it says all ports from 1-18 are in use.
4. I have tried to follow win7 instructions that directed my to advanced system properties and the environmental variables/system variables - this section I can't find in windows 10 ....
The only other option seems to be hacking the registry, which I will now look at....

I tried to use a USB headset plugged into my keyboard's spare USB port. I found it didn't work and at first I thought it was an audio issue, but trying to connect my kindle via that port didn't work either. I then tried using the USB ports on my monitor and found neither device worked on those ports either.
The ports on the front and back of my computer tower are working fine, but no device is working or even being noticed by the computer when plugged into any 'hub' ports. This occurred without a restart from the time I was listening to a video via headphones via the keyboard port just an hour before the problem occurred, and I'm not aware of any driver or app changes in that time.
I've tried avast, malwarebytes, plenty of restarts, checking legacy USBs weren't somehow disabled in BIOS, updating every driver I can think of via Device Manager, manually and even with 'DriverEasy' for good measure. I tried each of those steps both before AND after a system restore rollback to Friday. I also tried CCleaner, and of course over twenty restarts at this point. Device Manager looks like this right now: [URL] ......
I can't get that alerted Multimedia Audio Controller to update despite reinstalling my audio card drivers and realtek several times each now, but audio isn't the problem, just a symptom as the speakers I run through my TV as a third monitor are working fine and so are the headphones when plugged into the tower. I don't think that's the problem.

I am having a weird issue with Windows 10 on my custom built machine. I have Windows 10 Pro version 1511. I just today started having this issue. I am assuming it was after the latest update because I had no issues on the initial bootup.
I fired up the pc, logged on like normal, and nothing out of the ordinary happened. Windows tells me it has an update installed and needs to reboot. Not doing anything important, I decided to reboot and get it out of the way.
Well, upon rebooting, it goes to my locked screen like normal. I click on my mouse to bring up my pin screen to unlock the pc, and the mouse won't work. I look at the bottom of it, and the optical light isn't even lit. Keyboard's number lock light is on, but nothing on the keyboard responds either. I turn on a USB audio interface I have, and it shows that it won't connected to the pc like it should either. It is like all the USB ports are dead.
Not knowing what to do, I hit the old reset button, and boot into my BIOS. Mouse and Keyboard work fine without any issues in the bios pages. Load back into windows, and I notice that the mouse's optical light is on, UNTIL it loads windows up. It then goes dead.
I tried taking a PS2 to USB adapter to the PS2 port, and that didn't work either. Eventually, after I leave it sit on the login screen long enough, the USB ports become active and I can finally log in and use it like normal. But it takes literally 5 to 10 minuets. I check device manager and it does not appear that any USB drivers where updated or changed.
So far, I have rebooted twice and the problem happened at both boot ups, but eventually the USB ports kick on and let me log in. After I log in everything seems to be working fine.
