Hardware Drivers :: USB Ports Do Not Recognize Some Devices
Jul 8, 2014
My usb ports do not recognize some devices. Sometimes when I plug one device another one is unplugged., some times a specific usb port works, sometimes it doesn't. eg: when i unplug the mouse nw and plug it again it will stop working. if i plug another device eon a different usb port the mouse is disconnected. I went to control panel devices Manger and uninstalled every usb port and enable it again with no results.
I have recently bough a new PC. Now that everything is put together and installed I am facing only ONE problem.
I own an Adata Nobility NH13 External HDD which is USB 3.0. When I plug it into any USB3.0 port using a USB3.0 cable, the drive does not show up in My Computer, nor in Device manager, regardless if I use the Front or Rear USB3.0 ports.
The USB2 ports work just fine with it but what is the point in having a USB3.0 device if you don't use it the way you should ... If I plug in USB2 devices in the USB3.0 ports the work great, and even if I connect the ExtHDD with a USB2 cable it does work.
Now, the first thing you would think is that the USB3.0 drivers are missing but in the Device manager, unser USB controllers, there is a Intel(R) USB 3.0 eXtensible Host Controller-0100(Microsoft).
I am having problems with USB 3 devices disconnecting and reconnecting all the time when they are plugged into the Esata ports on the back of the motherboard in my sig. The USB 3 devices work ok in the normal USB 2 and 3 ports on the motherboard but I am not sure why they are not working in the Esata ports? I'm running Windows 8.1 with all the latest drivers and I am also running the BIOS f7e provided by Gigabyte to see if this would resolve the issue but it's not worked. If I connect USB 2 devices to the Esata ports they work ok, but could they possibly be faulty as they are not working correctly with USB3 devices?
I'm having an issue where if my USB devices are plugged in when i start my computer they are fine. but if i try to plug in a thumbdrive after it's already been turned on it won't recognize it. nothing.
Just Ran the SFC /scannow and i don't know what to make of it. it is attach The Attached file has the SFC details. not sure what to make of it.
Running Windows 8.1 x64 Gygabyte: z68a-d3h-b3 (will attach more if needed.)
I have run into a problem with my Windows 8 computer once in a while, it's that my PC doesn't recognize USB ported devices as supposed to, but it does recognize things such as a wireless mouse and keyboard. Now, my question is, can I buy a wired Xbox 360 controller and connect it to my computer, and trust it to download the drivers correctly, and work like it's supposed to? I have got a new game, and really want the controller to work for it.
My friend happened to look in Devices and Printers, and in the Multimedia Devices section he had about 10 devices showing up that he never heard of. Six of them were computers with names that he had never heard of, the others were devices that we could not tell what they were.
I expect that these entries mean that at some time they were on the same network that he was on. Would that be correct?
If so, then it is a matter for concern because he never goes on public networks. He only goes on his network at home, and a network in a small office that he rents and shares with one other person. They have their own router with security set up on it, and that router is connected to an Ethernet jack that most likely goes to a switch on a network that also provides internet service to some other offices in the same building.
This computer is only about 2 months old, so these entries can't be too old.
When I looked at his computer, he was on his home network and all those other devices showed as Offline. I right clicked on them all and removed them. Would it be a good guess that perhaps the security of the network at his office was compromised, and those devices were connected to that network at some point?
I told him to monitor and see when they reappear, but he won't be back in that office for 2 weeks.
my USB 3.0 ports are not working with my USB 3.0 ext-HDD. It's an ADATA Nobility NH13 I don't have any other USB 3.0 equipment to test, but the ext-HDD works perfectly on my laptop and on my TV as well, so it's definitely not the HDDs fault.
When I plug in USB 2 devices, they work perfectly and at maximum speeds. Even the HDD does work when connected with a USB 2.0 cable instead of it's own 3.0 cable.
This behaviour is present on front as well as the rear ports.
In the Device Manager there IS a USB3.0 driver:
Intel(r) USB 3.0 eXtensible Host Controller - 0100 (Microsoft) Universal Serial Bus controllers Generic USB xHCI Host Controller PCI but 0, device 20, function 0 This device is working properly
I have a strange issue that started appearing when I installed win 8, all my USB ports seem to reset with no apparent reason on different time periods, from a few minutes to hours, its like I unplugged the thing that's in the usb, and put it back in, its really annoying since my wirelles is via usb so I loose my connection every time it happens, its not I hardware problem because when I switch to win 7 it runs perfect
I have checked the drivers for the usb and it says its up to date?
I don't know why but my external hard drive isn't showing up when connected.. Windows makes the connection noise when I plug it in but it don't show up in disk management, device manager or anywhere else... If I plug it into a regular usb port it works fine... And its a usb 3.0 capable drive it worked before....?" I tried the new hardware wizard in device manager and didn't see anything... drivers all look fine....
I have problem that just crept up, my rear usb ports are malfunctioning. when I plug my mouse in the light underneath it comes on, but the mouse is not operational. The keyboards numlock light doesn't even go on.
My front ports are working now, but this is greatly inconveniencing me because, my scanner, printer, and headphones were plugged into there and now I have access to neither.
This started as soon as I plugged my phone into the front usb port as I have done over a thousand times with multiple phones even of dubious origin with no such a result.
I have two programs on my hard drive. They both require access to a COM port. When I attempt to access either one it works fine, but I need to have both of them running at the same time---thus I need an additional COM port. When I setup either program, the available port appears (COM 3). It does not allow the entry of any other port or call up an additional one---with all the COM's available, it would seem reasonable to be able to use more than one port at the time! I am using a Dell Pentium Laptop (1545) with Windows 8.1 PRO. The computer has 3G of memory.
I have several printers at work all hooked up to a samba share so that the whole office can use them. We have Konica Minolta, HP and Lexmarks predominantly but some other brands as well like Kyocera.
I have a fresh Win 8.1 Pro install and i have installed the printer drivers via the Windows update mechanism for all the printers. Some i've added via the samba share some via direct ip connection.
For whatever reason i cannot add/delete or config any of the printer ports as seen in the attached screen cap. I've even tried the windows Administrator account to no avail. UAC is off and i have admin rights to the pc.
I have sought support on freenode's #windows channel and googled the hell out of this topic, to avail.
I have a new PC that a friend built for me, I've noticed that the wireless receivers for my keyboard, mouse and wifi aren't working properly when plugged into any USB ports (front or back, 2.0 or 3.0). The range for the keyboard/mouse is awful and wifi connection is very slow if it connects at all.
However, all peripherals work correctly when plugged into a powered USB hub, the range for keyboard/mouse is huge and internet/download speed is fantastic.
Everything is up to date and was installed correctly. Having a couple of forums and speaking to Asus, I think it's a power issue. I arranged an RMA but the problem persists with the new motherboard.

I have Silicon Power Blaze B20 flash drive, which is not recognized by my desktop PC's both USB 3.0 ports. The flash drive's light blinks when pugged in, but no reaction from PC's side. I have tried to plug cord between flash drive and PC, but no change. It does recognize the device when plugged in any other USB 2.0 port. And the device is being recognized by other computer's both USB 2.0 and USB 3.0 ports, so I assume it is PC's fault, but what it is. My PC's USB 3.0 ports do recognize any other USB 3.0 devices - my external HDD, other USB 3.0 devices but this drive.
And it happens only when I boot the computer up and find that neither my keyboard or mouse are working then I plug them into front (2) avaialable usb ports and they work fine....
And then If I try to uninstall universal bus controllers by device manager then my keyboard + mouse stops working (obviously) then I shutdown via power button .... plug keyboard+mouse again back to rear usb ports... and they start working till few days...
I'm on windows 8.1 x64 with latest updates and all latest drivers etc...
The funny thing is this problem is with me since last 2 years or so... and I changed 3 Power supplies since then and luckily one motherboard, changed 3 mouses and 1 keyboard, 1 Hard disk too
even if they are plugged in rear ports I get "USB Disconnection" sound sometimes....
now thinking about buying a bluetooth keyboard + mouse but there are other things that needed to be plug in into rear ports... or should I go for an internal USB 2.0 PCI card ?
I'm using Win 8 on my laptop Lenovo G580. I have some problems with it. When I restart my laptop it takes too much time to restart and sometimes all USB ports doesn't work properly, means it shows Modem, USB Mouse, Pen drive connected but doesn't work. Here is the link of Dump file on Skydrive..
I have a Samsung SE-218 External DVD drive, and I cannot seem to access it in Windows 8.1 (though I have not had a chance to try it on any other computers yet, so there is always the possibility that something is wrong with the drive). Whenever I plug it in the light comes on and it will spin the disc for a bit, but nothing shows up in File Explorer or in Device Manager.
I've tried the command prompt command noted in this thread with no luck:
I have a sony vaio pro laptop, originally running windows 8 but just updated to windows 8.1. However, this problem was the same when I had windows 8 so updating to 8.1 has not changed anything. I cannot add my xbox 360 wirelessly as a device to my vaio laptop. I want to be able to stream videos etc from laptop to xbox. When I go to Change PC settings>Devices>Add device the computer searches but will not find the xbox, despite it being switched on and connected to the wireless network.
The really frustrating thing is that I have another laptop running windows 8, now updated to 8.1, and it connects with the xbox with no problems whatsoever. As soon as I click 'add a device' on this laptop the xbox is found and I can connect to it/stream content with no problems.
I have tried disabling the firewall on my vaio laptop, still didn't work. I have ensured sharing etc is turned on on both the laptop and the xbox.
Just upgraded to Win 8.1 Pro from Win 8 on a Dell Latitude E6530. Everything was working fine; post upgrade, system does not recognize any of my SD cards upon insertion. [Don't even see a drive letter show up.] All other peripheral storage devices are fine.
I have recently purchased a new HP Officejet Pro 8620 and am currently having problems actually using it.
I have already installed the full-feature driver from the HP website but the printer does not appear in devices and printers. However my printer does appear in print dialog and the device manager. I have tried adding the printer through devices and printers but it has no effect.
When I try to print anything through print dialog or any application for that matter no print job is sent. Basically I can't print anything from my computer now.
I have already re-installed the driver multiple times only to come up with similar results. This is for my main computer which is a HP Envy dv7. Also I have connected to the printer via the wireless router option.
However for my second computer which is a Dell XPS 12 everything worked fine right from the start which also connected to the printer wirelessly.
I have a weird issue in which after a boot of the machine it will take some time for USB devices to become initialized, yes... this includes my USB keyboard and mouse. So essentially even though the system may be up and running at the user logon screen, I have to wait five seconds until I can type my password in on my USB connected keyboard.
I have recently built a new computer and installed Windows 8. All was running fine (including USB devices such as iPhone, flash drive etc), however since upgrading to Windows 8.1, none of my USB devices are showing up at all. Oddly, the mouse and keyboard still work.
When I go into the BIOS, all my devices (iPhone, Flash drive, keyboard and mouse etc) all show up in there, so I'm guessing it's a driver/Windows 8.1 issue that I'm missing?
I have been to the ASUS website and downloaded all the drivers I can find, but still no luck.
My motherboard is an "Asus Z97 Pro". I have tried contacting Asus support, but they are completely useless!
New printers do not display in Windows 8.1 Devices and Printers (no icon):
New Dell, clean install:
- Reinstalled Dell Factory Image - Updated to Windows 8.1 - Installed Office 2013 - Added BUILT-IN Windows Driver for LaserJet 5P/5MP - Added Epson driver for Windows 8 64 bit from Epson website Neither printer shows in Devices and Printers.
Rebooted. Stopped and started print spooler. Checked registry and all printers, including the new ones, appear to be listed in all the correct registry areas.
Open Notepad, select Print, both printers are listed.
Both printers print. When in Notepad, select Print, I can right click on the printer, select properties, and control the printer, print test pages, change drivers and preferences, etc.
The ONLY PROBLEM is the printers do not show in Devices and Printers, so I cannot control them from there.
I have a Dell Inspiron 660 PC w/windows 8.1 no matter what I plug into the usb port I cannot find it on my computer. I hear the connect/disconnect sound, but can't find anything on the computer as to where it is at or how to open it. The device is a storage device with photos. It also does the same thing with my phone. I hear it, but nothing opens or comes up anywhere.
When I go toControl Panel -> Hardware and Sound -> Devices and Printersit can take 5 minutes or more to populate the window. A green bar slowly progressing along the top.
Sometimes (not always) when I click on the Network icon it shows an empty window, taking five or more minutes, also with a green bar slowly progressing along the top. EDIT: After I submitted this post I saw that the network window had finally populated. Still, it was incredibly slow and happened after the window showed a message saying "This folder is empty."
If I go to This PC that comes up almost instantly, including the mapped network drives.
