My PC does not recognize any USB connection

I found the solution; it was enough to uninstall all the components of the USB Bus Controllers and restart the PC, and everything is working like before.

Thank you for your help.

Hello,

after a complete reinstallation of Windows XP, I no longer have any USB ports connected. When I plug in a USB drive or anything else, the light on the drive lights up but it is not detected. What should I do??
Thank you in advance for your help.

Okay, problem solved. I had 10 USB ports because my motherboard can support that many. My USB ports weren't recognizing any devices because my Windows XP didn't have service packs 1 and 2, which include the necessary USB drivers to support the USB 2.0 standard... Apparently, my motherboard didn't even want to use the USB ports as 1.0...

Good evening,
I have the same problem you had with the USB connections.
No devices connect to my USB ports even though everything was working well before.
I read that you solved this problem.
What do you mean by "uninstall all the components of the USB Bus Controllers"?
Thank you for your help.

Check in Control Panel, System, Device Manager that your USB ports are properly recognized and that there are no conflicts. If there are any, reinstall the correct drivers!

Hello. My OS is XP and I have SP2. My problem is somewhat similar: my USB key has always worked fine on my PC. Since yesterday, my PC no longer recognizes it. I clarify that my key does not require a driver since XP automatically detects it. I tried my key on all four USB ports but nothing works. However, the issue does not come from the USB ports since my webcam, modem, and another key are working. It also does not come from my key since it works on other PCs and on my PS3. So where could the problem be coming from? Thank you in advance for your responses.

Not all USB ports are enabled in the BIOS.

Hello,
I also have a little problem with my USB ports.
They work with my hard drive and USB sticks, but when I connect my printer, it says:
"not recognized..."
And during the installation of the software, it does not detect it either!
My printer works perfectly on my other PC.
Thank you.

I have the same problem, but apparently no one has an answer to give.

Hello,

I formatted my PC, but I don't have the drivers which means it doesn't recognize any USB keys.
Please tell me how to download the driver.

PS: I know that each motherboard has its driver, so here is mine.
"Motherboard ID 62-1101-001131-00101111-040201-VIA_P6$MS9138E_MS9138E RELEASE 11/01/2002"

THANK YOU very much.

I would also like some answers.

I have assembled a new one with an ANTEC P180 case and an M2N SLI Deluxe motherboard. My USB ports are no longer working and I get the message: unrecognized device, the USB port has malfunctioned under Windows...

Additionally, I noticed that it shows 10 USB ports when I don't actually have that many.
Where is the problem? Am I going to "hardware" and uninstalling all the USB devices/concentrators/ports that are listed there?

I had a similar thing happen with my camera. Suddenly, after it walked automatically, my computer no longer recognized my camera. The icon appears at the bottom of the screen and that's it: radio silence!! I tried everything for a week, thanks to you!!! Checking the peripherals and a bunch of other things!!! A week of spinning my wheels! Until I REALIZED THAT IT WAS THE MOST PERFECTIONIST FORM OF ANTIVIRUS I HAD JUST INSTALLED THAT WAS BLOCKING ACCESS TO THE PERIPHERALS!!! Once I uninstalled this perfectionist antivirus, my camera and my photo gallery finally met!! PHEW!! If this can help...

Thank you very much, my problem is solved.

Hello!!

I came across your website because I have a problem, but I couldn't find the answer to it!!

Actually, for some time now, my PC does not recognize any USB connections (iPod, printer, webcam...) and I don't know how to resolve this issue!!

I hope you will help me solve this problem!!

I look forward to your replies eagerly!!

Thank you very much in advance!!!

Hello Mathieu,
I find myself in a situation similar to yours, it seems that I also don't have service packs 1 and 2 which include the USB drivers for the USB 2.0 standard. Could you please tell me how to recover them, as this is causing me a lot of trouble? Thank you in advance.

Many people seem to be having USB problems, and so do I! I have a Palm that was working perfectly with a floppy and a 6-in-1 card reader that was doing just fine before... I connected a Creative MuVo reader once and since then, it's a mess! Nothing works anymore, my Palm doesn't sync anymore and my card reader is no longer in the list (and it’s not a drive letter assignment error f:..g:...h:....)

All the answers I've found talk about going to the manager and updating the yellow question marks..... I'm not that much of a novice! My problem is much deeper than that... no updates possible, everything is OK.

I’ve uninstalled the USB hubs, rebooted, disabled the USB ports in the BIOS, rebooted, uninstalled all the Palm software or other that was supposed to work with USB.... rebooted, reactivated the USB in the BIOS..... XP recognizes the new hardware, installs.... but the card reader is still not there.....

I’ve been dealing with this issue for 3 months now, Palm has nothing intelligent to say to me, Creative doesn't understand the problem and tells me to contact Palm, and Micro$oft..... well, of course, it’s never their fault!!!

So what do we do in the meantime?!?!?

Hello, I have a problem, I have a Sony Cybershot DSC S90 digital camera.
It was working really well, and now for some time when I plug it into the USB port,
nothing happens anymore. The little window that usually comes up to read the photos
doesn't appear. It's quite complicated to explain, but in any case, I can no longer transfer photos to my computer.
It's as if my camera doesn't recognize anything anymore.
If anyone has a solution so that I can again transfer my photos to my computer,
thank you for letting me know.
Best wishes.

Bonsoir, j'ai un autre problème avec mes USB. J'ai un portable Acer Aspire 1703SM. Il y a quelques semaines, je me suis acheté un nouvel appareil numérique, et en installant le logiciel, Windows ne l'a pas reconnu. Je me suis alors acheté un lecteur de cartes, et c'est l'idem, il n'est pas reconnu. Entre-temps, je me suis aussi acheté un disque dur externe, et il n'est reconnu par aucun des 4 USB. Alors que mon ancienne clé USB, mon ancien disque dur et la souris fonctionnent. En fait, je ne sais pas quand le problème est survenu. Dans le gestionnaire de périphériques, il n'y a aucun point d'interrogation. J'ai désinstallé tous les contrôleurs de bus USB, redémarré Windows, mais je n'arrive pas à installer automatiquement. J'ai dû faire une restauration du système pour que la souris fonctionne à nouveau. Qui a une solution, merci d'avance;

As a nostalgic old man of arcade pinball machines, a former Atari user (from Pong to Calamus and Cubase...), I confess today my feeling of horror in front of USB tech that wants to be more than ever P'nPlay... a kind of "je ne sais quoi" about this fragile 8-pin connector prompts me to trust it almost blindly... are we really at the point where we even have to tinker with taboo things like: LOCAL host/USB forbidden/users lost/makePCIhost232/forget%... this thread has nothing relevant, I'm just giving a funny nod... (but since USB often seems so twisted to me!)
