Logitech unifying reciever no longer works on ALL USB ports

57

Solution 1

This is typical behavior of a broken/worn down unifying receiver. The only way to fix this is to purchase another. However, you'll have to setup your old devices to the new receiver using Logitech's software.

This may have to be done with each new computer you use the mouse/new unifying receiver with. Although after a fresh install of Windows 8, my receiver picked up the mouse just fine without any of the Logitech software.

Solution 2

I had exactly the same problem, just watched this simple video on YouTube.

Basically the steps are:

  • taking the black cap off
  • sticking a piece of paper inside making the contact points closer
  • stick the black cap back on

I tried it and it works.

Solution 3

A bit late to the party but this worked for me. For some reason the usb.inf file was missing or corrupt for me.

Browse to 'C:\Windows\System32\DriverStore\FileRepository\usb.inf_amd64_neutral_e2b28ecac19a29af'

Copy usb.inf and usb.PNF to 'C:\Windows\INF\'

Update drive on unknown devices

-- In Device Manager, right-click and select Properties

-- Select Driver tab

-- Click 'Update Driver' button

-- Select 'Browse my computer for driver software'

-- Enter 'C:\Windows\INF\' in the Search for driver software in this location field and click Next

Solution 4

If the Receiver isn't being recognized it is not necessarily broken. I plugged my t600 receiver into my pc (win 7 64bit) and i am having these same problems. I move over to my laptop (windows 8) with the same receiver and i can use the mouse with no difficulty. There is something about windows 7 64 bit that is having issues with this. Test your receiver on a different device before claiming its broken. or returning your product. Chances are you may be able to make this work.

Solution 5

I'm pretty sure I ran into this problem after Acronis Backup & Restore 11.5 imaged my disk to a .tib file.

Both the source system and the target system were apparently missing C:\windows\inf\usb.inf afterwards.

I copied it over from my netbook and an 'Update Drivers' later, had my logitech k400 wireless keyboard working again.

This seems to have affected not just logitech unifying receivers, but all USB Composite Devices. My Android tablet is also affected, as well as my Microsoft Xbox 360 USB Controller receiver, since it has two 360 pads sync'd to it, but my wired PowerA Minix360 is not affected. My microsoft wired keyboard 600 and logitech V220 are also not affected, as they are not 'USB Composite Device', but 'USB Human Interface Device'.

USB Composite Device is used to wrap up multiple child Devices in a single parent Device, such as two USB Human Interface Device endpoints (One for keyboard, one for mouse) like the Logitech Unifying Receiver does.

Big thanks to lucvdv of answers.microsoft.com for figuring it out:

Some time ago, my system stopped recognizing some, but not all USB devices.
USB ports are fine, it reads the device descriptors but then either says
it's unknown hardware or says it can't find a driver for it.

A second symptom that must have started at the same time is that it
"forgets" all about some USB devices that have always worked fine before, 
with the same result: suddenly either "unknown" or "can't find a driver".

Two weeks ago, it was my keyboard.  
It still worked when I logged on (it had to, I used it to enter my password).
Immediately after logging on, the found new hardware thing popped up,
after a few seconds it said it failed to install my new hardware, and at
that moment my keyboard stopped working.
Never found a solution, I've been using a PS2 keyboard instead since.
I've tried other USB keyboards, it didn't recognize any of them.

Yesterday, it was the USB hub that's built into my monitor that
suddenly turned into an "unknown device", and nothing I connect
to it is detected anymore. 
In an attempt to fix that, I launched the device manager and let it
scan for new hardware.

Result: instead of my USB hub starting to work again, my 
Logitech wireless mouse stopped working. 

The "USB receiver" is now listed with an exclamation mark,
"drivers for this device are not installed".  
It worked fine just a few seconds before. 
Right now I'm back to using a wired USB mouse, but I wonder how
long that's going to keep working.

It's not the receiver that's at fault: when I plug it in,
it shows up in device management with the right name and device ID:
USB\VID_046D&PID_C52B&REV_1201 - USB\VID_046D&PID_C52B,
and status "The drivers for this device are not installed. (Code 28)".

Comparing the contents of %SystemRoot%\Inf to another Win7-64 system,
I noticed that file USB.INF was missing.
Copied it over from the other system, started device manager and
re-installed drivers for the non-working devices, and the problem is fixed.

Thanks for your patience in tracking it down, lucvdv!

    In my test case, I'm up to aligning in columns an input with its label and a hyperlink. The problem is that hyperlink gets aligned to label, and not to input:

    enter image description here

    The code is as follows:

           <div class="row">
    
                <div class="form-group col-xs-4">
                    <label class="form__label" for="form__field__recipientId">Código
                        beneficiario </label> <input class="form-control input-md col-xs-8"
                        id="form__field__recipientId" name="form__field__recipientId"
                        type="text" placeholder="Introduce ordenante">
                </div>
    
                <div class="form-group col-xs-4">
                    <a class="form__side__hyperlink" href="">Buscar beneficiario</a>
                </div>
    
            </div>
    

    I have tried many things, mainly form-inlining the elements, but I don't think I'm doing it correctly since I end up messing things up.

      This is NOT behavior of a broken/worn down unifying receiver. I've just plugged in my Desktop and everything is working fine!

      @MaratKoshoev did you plug it into another usb slot?

    I had found this video too, does in fact work, in fact the intermittent behaviour i had, working on some ports not on others at random times, the idea that the contacts were not contacting properly made a lot of sense.

    I have the same issue just now. Unifying receiver(s) works only in one USB-port and everywhere else I've got "Unknown device". Manual driver installation fails too. usb.inf was absent but search over disk C:\ shows five identical copies. After copying that file into c:\windows\inf\usb.inf and reboot everything works like a charm!

    I can also confirm the solution works. I tried it yesterday and have had no more problems. Also, the problem was in Windows and Linux, so I was able to quickly narrow the issue down to hardware.

    I was able to fix using a modification of this technique, since I couldn't get the cap to pull off. When I was pulling on it, I noticed the contacts moved up and down. I bent it enough to push the contacts up a bit and now it works fine..

    That fixed several driver issues for me. I don't know why Windows didn't search 'C:\Windows\INF\' by default.

    This works only because the metal contacts on receiver pcb are worn up to a certain length and when you do it, you give it a tiny extra amount of metal. This will work only temporarily, until you plug/unplug it several times and the extra metal scrathes off too. I tried it at first, but the receiver died after few weeks again. I got it working again by cleaning and covering the contacts with tiny amount of solder and putting a new metal on it, but again it worked only for some time, and it's dead now. Strangely, this time the new contacts I made are NOT worn off, so there must be more to it.

    This is going to mess everything. I don't recommend using it on row with BS3.

    That's why I asked to give another class name for that div and give the styles to that particular class.

    positioning using absolute is not a good solution for this problem. It may cause issues in responsive designs. So the better solution is to use flexbox instead.

    Hi Abinthaha, I've tried your approach. While it does the trick, it does mess the form structure. I have tried to replicate the .row class into a .flex__row, but still changes the spacing between elements. Thanks for the flex value, didn't know about that :)

    I'm sticking with this answer, since I can isolate this kind of element (input + hyperlink aligned) more easily.

    flex is the latest css3 display property. once you just know it, you can create any structure using it. That's its advantage. Yeah, of course, there is a possibility that your structure may get messed up. give flex-grow: 1 to the direct child (.form-group in your case). Instead of applying it directly, give another class name to it and apply the styles to that class.

    I only had the receiver a few weeks and it already does not work anymore. When I move the black cap, I can see the contacts on the other side moving up and down.

    That indicates your port or receiver were faulty and/or broken.

    This seems to be the correct, very helpful, answer to a different problem. A quicker short-term fix for me was just to press downward on the dongle to create a better contact.
