USB Ports Stopped Working?
Dec 28, 2011
I am in a spot of bother since I have to give an important presentation and all of a sudden my USB ports (3) in HP pavillion dv6(running windows 7 64 bit) stopped working. I plugged my friend's ipod touch to charge from the computer and it did not work and after that none of the ports will work. I tried reinstalling the drivers,restarted the computer multiple times and even ran a virus scan but its of no use.Out of the 3 ports only one says "windows detected a problem with the device", the other 2 wont even say anything. I even checked at the registry keys to see if the USB ports are enabled and they were fine. My warranty expired this December so now I have to pay HP for any trouble shooting

Both USB ports at my laptop (Toshiba Satellite C650, Windows 7 home premium, SP1, x64) stopped working after plugging in and unplugging several Garmin Forerunner 305 watches in a row. Everything looks all right in the device manage (no exclamations marks). I have reinstalled everything that has something to do with USB in the device manager, several times. Updated BIOS and used Windows update to get all the latest drivers and fixes.I have taken out the battery and let the computer "rest" for several hours without any power supply.I have tried to do some changes in registry key according to these instructions: USB ports suddenly stopped working in Windows 7 RC1 - Microsoft Answers (I managed to delete Lowerfilters).And of course I have tried with different USB-sticks, mouses, external hard drive etc. There is no power in the ports. When I plug in my Garmin Watch it does not charge.I installed and tried two registry cleaners (TweakNow RegCleaner 2011 and Glary utilities). After using them I got some hope back when I got a bit of reaction from one of the ports. A few times after plugging in something it started to install the driver but stopped immediately - telling me that the driver cannot be installed because the device is not plugged in (while it is).
I consider to do system restore to factory settings but before that I have to copy and save everything which is a bit complicated since non of the ports is working. If the restore to factory settings does not work, then I believe there is a problem with the hardware and I have to get the motherboard replaced.

I have a Compaq Presario CQ62-215DX, running Norton Internet Security and firewall through Windows 7. I sucessfully installed new Wireless LAN and Lightscribe system software several days ago, along with the Live Essentials, Realtek and Windows 7 Updates. Everything was operating correctly yesterday, but when I booted up my computer today my wireless mouse refused to work. After trying a fix involving a USB stick, I realized that none of my USB ports work. The ports light up when I restart, until Windows 7 finishes logging in, and once it begins the drivers refuse to work. Is it because of the recent updates? Because I cleaned up my back-up copies?

My USB ports on my ASUS c90s laptop suddenly stopped working one by one. After reading around the internet it seems this is a windows 7 problem. When I go to device management I have other devices not working. Two Base system devices under a PCI bus category and an "Unknown Device". The unknown device is under the Intel(R) 82801GB/GR (ICH7 Family) LPC Interface Controller - 27B8 section. It has no driver, even though I downloaded the driver manually it still doesn't work. I've tried removing my battery and then replacing it. I disabled all the USB ports then restarted. I've even uninstalled them aswell as the unknown device.I went to theregistry:HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{36FC9E60-C465-11CF-8056-444553540000}and found one solution to delete the upper and lower values. I had no lower values just a "lowerlogoversion" but I did delete the upper value. I then restarted and attempted to plug my mouse into my USB again and it was recognized for about a second and the red light under my mouse lit up but then went away.

I have an older Dell Inspiron 5100 that's been rock solid since day one. I recently transferred all my music from my PC to my Seagate FreeAgent GoFlex so I could organize my files while I was out of town on business. When I got to my hotel and plugged the Seagate into the USB port the laptop would not recognize it. There's two USB ports, one of the USB ports does nothing at all when I plug the drive in (not even a 'Ding-Dong' sound). The other port at least responds but still not recognized. By "responds" I mean Windows responds with a "Dunn..." sound; not the happy two tone sound of a device actually being recognized and available, just a "Dunn..."I've used this drive before on this laptop on several occasions so I know it's compatible. I also came home and plugged to drive back into the PC to see if the drive itself responds. It does, and all files are there and happy. Also, when plugged into the non-responsive USB slot the light on the drive blinks a couple times, the platters spool up for 15 or so seconds then goes out. When plugged into the other USB slot (the one that goes "Dunn...") the light comes on and stays on and the platters spin untill I unplug the device. But it's still not recognized.

I was playing my laptop one day right? And my ports stopped working out of nowhere. Like no joke i was playing my laptop nice and calmly and then Bam they stopped like they busted... I have one way I read about fixing it: Hit F8 or del when comp is powering up and hit "Load Optimized Defaults".

Basically, my HP DV6-3065EA running Windows 7 Home Premium (x64) laptop died. I went into a computer shop and asked how much a simple diagnostic test would be to find out how much a repair would be. He quoted me 90. Phew, jog on! That wasn't going to happen!Anyway, I decided to replace the power jack. No hard job, just a simple unplug and plug back in job. (looks abit like this Hp power jack image by chikyeung on Photobucket). I replaced it; everything is running fine. I tried to put a USB pen drive into a usb socket. Didn't work. Tried another, didn't work. I have tried several devices and they all work on other computers but don't seem to be working on mine. I have been trawling the internet for answers, and as of yet, nothing -.-! I wouldn't call myself a novice, trust me, I've tried everything, uninstalling and reinstalling all of the USB drivers, checking bits of the registry.etc. Nothing. So today, i thought, right, WIPE THE COMPUTER! I backed up everything, went back to scratch.

Recently my computer has been force closing applications like Photoshop and Windows Explorer. It usually happens when I right click in Explorer or try to open anything in Photoshop. When it happens, a dialogue box comes up that says "Windows Explorer has stopped working" or "Adobe Photoshop has stopped working" Under the details it displays this information:
Problem signature:
Problem Event Name:APPCRASH

I am not going to tell my problem or trouble but rather to tell what I had done based on what I found out from other responses to "related issues" subjected above.I just thought that I must do this for the sake of others, brothers and sisters in Jesus Christ wanted to go back to the threads that his but I am not that fond of using the search fields and somehow my google search results on this lappy is quite differ from the one i got on the usb-troubled lappy that i used to log into sevenforums. i have read through just about 10 of the related result on sevenforums but not one of them is the one i found out earlier.anyways, what i did was: uninstalled all usb listings in device manager and then just shut down the lappy, unplug all cables including power cable and went out for a smoke. a few minutes later, came back and plugged the power cord and turned on the lappy. and somehow, windows auto-install everything and since the lappy is wirelessly connected to the internet like always, it also download and install everything.then i plug the main cause of the problem (microsoft 5-button intelligent mouse) and wait for the driver update wizard to complete; and now everything not only seems working fine, BUT actually working fine now.

Lately some of the usb ports of my computer are not working properly: any device connected to them is not recognized. The problem appeared after I triedunsuccessfully to recover data from a damaged usb stick using umptool2090. This is how the ports appear from the Device Manager (it's in Italian, but it should be understandable):If I uninstall the usb controllers and re-install them automatically (using the device manager), the ports start working, but the problem reappears after rebooting. My motherboard is an Asus M2N78-LA (Violet6) and my operating system is Windows 7 home premium SP1. What can I do?

I have three USB ports on my Gateway laptop and none of them are working. I've tried un-installing them through the Device Manager, but the action gets hung up and I have to stop it (I've let it run for 10+ minutes) through the task manager. When I re-open the Device Manager the USB all the controllers are still there.
I bought an expansion drive because I wanted to back up my photos and other files. After I did that I was going to reinstall a clean version of Windows 7 as my laptop hasn't been working well lately.
USB ports would be greatly appreciated.

I have windows 7 and linux mint on my desktop, I built my computer myself, and it works great. My girlfriend asked me to help her put songs onto her iPhone 3G this weekend so I plugged it into my computer while in windows and a little bubble popped up saying a usb port was using too much power, or something along those lines. I didn't think anything of it because nothing else happened. The iPhone had been acting really strange lately so in the end no music got put onto it. I restarted my computer and none of my USB ports work anymore. My mouse and keyboard are USB and now I can't log onto windows because I can't type in my password.

For the past month or so I've lost complete access to my USB 3.0 ports. They do nothing - NOTHING.
I've gone the route of reinstalling the Intel chipset drivers and USB 3.0 drivers from Intel and from HP. When I plug anything in to the ports, it's as if I have done nothing at all.Thumb drives are not detected, it's as if the ports have been disconnected from the motherboard. USB 2.0 and 3.0 external drives are not detected, nor do they attempt to spin up or show any activity on their LEDs.
I've also gone the route of reinstalling the OS from the ground up (I hate the loads that OEMs put on their systems!), only installing HP drivers and apps from the HP website. I've also done the same but only installing drivers from the Intel website - again - nothing.
Nothing related to USB is showing up in any of the event logs. The one single USB 2.0 port works fine - 100%.
