USB Ports Have Suddenly Stopped Working?
Mar 31, 2011
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?

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.

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 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

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 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".

Now i get nothing. no charge, no recognition.

My LAN and WiFi suddenly stopped working. It was working fine for several hours before now. I decided to take a break and pour myself some coffee and give a package to the postman. Gone for maybe 10 minutes at the most.When I came back, the LAN and WiFi mysteriously had stopped functioning. I know nobody touched anything because I am the only one who uses this computer. I tried disabling and re-enabling, as well as re-installing the drivers. This is a work network, and everyone else's connection seems fine, and I can't seem to figure out what's wrong. Keep in mind I can't just re-set the router because this is not a home network.

The first thing I do after installing win 7 is apply the uxtheme patch. I've been running custom themes for a while, but yesterday decided to change the look of things. I applied a os x leopard type theme, it didn't work and now I've lost all desktop visual effects (transparency, themes, win+tab).I run the diagnostic and it detects that 'Windows Desktop Manager is disabled' - so I think "Ok, I'll just go into services and re-enable it"... but it's GONE! How the hell can a service just remove it self?So I run System Restore back to when I knew it was working, but still no damn transparency, that service or themes, just the default non-transparent Aero!

I've had WMC up and running for about a year now, no problems. Tonight we decided to watch a movie that I have as an *.mkv file - we do this all the time, at least once a week if not more. I shut down WMC and played the movie in VLC Media player. When I went to start WMC again, the sound was gone. The sound works in the rest of the system. I can hear computer sounds, and VLC and other media players work fine. It's just WMC that has no sound.I checked all my devices and drivers, no errors. Though to be honest, if that was the problem I'd expect all sounds to be gone.I removed WMC from the system by using the "Remove Windows Features" in Control Panel, and then re-installed it. No difference.I did notice however that removing and re-installing WMC, I didn't have to re-setup all my channels, etc. The settings "stuck". (Oh, by the way, I did re-run the sound setup in WMC, no difference).I'm wondering if maybe my WMC settings are corrupted somehow? Is there some sort of config file perhaps? I have no backup plan here, this is my only way to watch TV. I guess I could wipe the drive and start from scratch, but I'd prefer not to.

I run an eyefinity setup with a 2gb 6870, and for about 2 months it has been running perfectly fine. I turned my pc on this morning and my third display stopped working.Details Currently monitors 1,2 are on.When the pc posts the post info is on monitors 1,3 which shows that the third monitor is recognized.(Does not show up in CCC)Im using an active dp adapter for monitor 1. Dvi for 2 and Hdmi for 3. I have switched all of these around and it makes 0 Difference. The ADP adapter monitor works when it is plugged in so I am not sure if the cable went bad. I figure if the cable went bad it would not work at all.I have tried re installing the drivers and reverting to an older issue of ccc. Neither worked.

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.

Last night my router was working fine, and then all of a sudden my Internet stopped working. when i woke up i figured out that with a Ethernet cord the Internet works, but going wireless doesn't work. its not in my computer since it also wont work on my ps3.
When i try to connect to it, it either says it cannot connect, or connects and says i have Internet but doesn't let me actually load anything.

I have a Trust TB-4200 A4 graphics tablet
Installed it over 6 weeks ago in windows7 RC 64bit with Vista drivers.
works perfectly
turned my machine on today and suddenly its stopped working with this:
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
I haven't touched anything, havent changed anything, I've done nothing.
Why the hell has this happened? I'm screwed now and have to pother about dual booting into XP just to get my artwork finished
Why has Windows 7 suddenly decided to block my drivers that have been working perfectly fine for 6 weeks for no reason!?

I had to re-install Mozilla Firefox and ever since then, my links/hyperlinks in my emails (Microsoft Outlook 2007) won't work. It may have been other things that I installed which led me to have to re-install Firefox, but I just need to be able to get the links to work again.

My Seagate GoFlex 2 TB USB 3 drive has suddenly stopped working. When it happened, I was having many issues with Windows (for about 10 minutes and 3 reboots). It seems to have calmed down now but I am still having problems with USB devices. When I plug the external HD into the top USB ports (next to the wireless dongle for keybd/mouse), the keyboard stops working. In the system error logs I am getting this critical error: The driver DriverWUDFRd failed to load for the device RootSIDESHOW000. I am also noticing that I have an unknown device in my device manager. I am also having a message come up when I start the computer saying that Windows cannot connect to the Group Policy Controller. It says that it is timing out. [code]

I was playing League of Legends when this happened and when the game loaded into the world the mouse just stopped responding and never kicked back on. I've restarted the computer, pulled the battery for a few minutes, turned legacy usb on/off, right click and uninstalled all universal USB controllers (then restarted to get windows to reinstall them), tried different mice on the problem computer, tried the mouse on a different computer (it worked), pretty much every solution i've found on the internet so far from people with similar issues of usb mice/keyboards suddenly stopping and never coming back using windows 7.I'm actually going to go to toshiba's website and check if they have any drivers that I could download/update.

I realize the title happens frequently in general. I myself have had to go in and restore the device countless times on reboot. That's not the issue (default device, device enabled, etc).For some mysterious reason, my What U Hear is malfunctioning and picking up absolutely nothing as of last night's reboot. Prior to this for the last few years since being on Win 7, I've had no issues (other than the common restore the default, enable it, etc).
1. I had a power outage mid day yesterday. I'm pretty sure I didn't attempt to use my What U Hear after this outage, but DID use it just prior to the outage (but was not recording or anything when the outage hit, but SF 9.0 was open)
2. I have gone into the BIOS and disabled HD Audio (since my MOBO has onboard)... I really thought this second one was going to fix my problem, but no.
When I go to check my devices in the audio pop-up, it shows my speakers as the default playback device and the oscillator goes as I play something. When I look at the recording tab, with the What U hear device enabled & defaulted, the oscillator just sits there dead. When I go to properties and either select "default playback device" OR select my external speakers (both of which should be the speakers, WHICH DO oscillate and work just fine) it doesn't matter... What U Hear still does not pick anything up!

A few days ago my computer (an ASUS Eee Netbook) suddenly stopped being able to connect to the wireless network in my apartment, seemingly for no reason whatsoever. It had been working fine earlier in the day, I went out for about an hour (didn't even shut the computer down), returned home and was unable to connect to the network. The computer can locate the network and continues to attempt connecting to it with no luck. I can connect to other networks without any trouble. It has never done this before. I've rebooted the computer several times and performed a System Restore, but without any success. I'm hesitant to reset the router as this is a shared connection with the other people in my apartment (who as far as I know aren't having any trouble with the connection).
