USB's Ports Not Working Properly In Windows 7?
Sep 17, 2011
My system is Dell OptiPlex 740, 2.50 GB RAM, Win 7 Ultimate 64bit.All of a sudden - the USB ports (all 7 of them) stopped to function roperly.Each device I plugged into the port - got recognized as 'uknown device' and doesn't function at all.One of the biggest problems that this cause me - I can't plug in the keyboard and the mice - I don't have PS/2 ports in this computer.Thing is, even out of Windows, the USB doesn't work. I'm suspecting this because the PC giving me 'Keyboard fault' everytime I restart. So I can't got to BIOS either.Right now I'm using special combination of USB hub attached to one of the ports, and the peripherals connected to the hub

It seems all the usb ports do not work on my laptop. My usb mouse doesn't work, and my other usb devices do not work either. All the usb drivers are installed properly as detected.

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.

I'm convinced that that is the problem. I have tried EVERYTHING else to get the USB ports to work, but still no luck. They will not recognize any devices that I plug into the computer. Here are the specs (copied from hp.com):
Hardware
Product Nameze2108wm
US Product NumberEA390UA#ABA
Microprocessor1.6GHz AMD Mobile Sempron™ Processor 2800+ with PowerNow!™ Technology
Microprocessor Cache256KB L2 Cache
[Code].....
I found a Windows.old file under the C drive, so that's what I figure happened.
Is there any way to make the USB drives work without having to revert to Windows XP? Also, are the ports not working simply because the drivers are not compatible with Win 7, or is there another problem (probably something simple and then I'll feel like an idiot =/ )?

I have recently installed windows 7 on to my pc. Everything seemed okay to start with, but then the printer wouldn't work. The printer is working, but not with the computer. The message that usb ports arent working keeps coming up.
I have tried to uninstall the usb drivers, to no avail. Keeps saying usb device not detected.

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.

USB Ports Stopped Working - Windows 7?

my usb ports (mouse and keyboard) stopped working after it gets to windows welcome screen. It worked prior to that (I could get in to the bios and use the keyboard there) and I can even get to the windows repair mode and have my usb mouse and keyboard working. But booting it normally (or even safe mode) will disable keyboard and mouse (and all usb ports i believe) at the login screen. I don't have a PS/2 port so I don't have any alternative way to type in my pwd at the login screen. I would like to try the solution posted above, since I can get to the repair mode, open command prompt and run regedit, but just unsure since I didn't see any response from the user on that post whether it worked or not.

Left my computer running Win 7 home premium on overnight, had just installed a fresh copy of windows. I saw a message saying the system was restarted because of windows updates. Now, none of my USB 2.0 ports work, neither the rear ports nor usb mobo headers work. The two usb 3.0 ports do work however. Those 2.0 ports were working fine previously. Never seen update do this before.

last night after applying a windows update none of my usb ports work. I have four onboard total. After installing the hotfix last night, two of them worked. After a reboot this morning im back to square one. Now last night before i got it briefly working, whatever i plugged in would charge but not be recognized by windows. Now i get nothing. no charge, no recognition.

I have recently downloaded Windows 7 - 32 bit onto a new discrete (i.e. Physically separate) HDD. In the installation process it had severe problems with USB and PCIe drivers. That is they don't work and there were! marks in Device Manager. I was lucky in having access to an old PS2 kybd which allowed me some access to the new os. Luckily, since I was booting off of a Windows XP Home Edition on a separate HDD I managed to use its drivers which worked on the Windows 7 and allowed me to get my USB kyybd and mouse working again. It also automatically down loaded the other drivers for my devices like the USB dongle for wireless internet access.
This is a long preamble to my actual problem and the reason for this message. I have not had as much success when I tried the same exercise; this time with Windows 7 - 64 bit installation. The 64 bit was installed on a separate partition on the same physical drive as the 32 bit version. The 32 bit drivers from Win 7 - 32 bit and XP don't work. I thought the 32 bit drivers for such basic things as USB pointing devices would work in the 64 bit version; but clearly not. Also, clearly my installation disk is negligent in not loading the drivers in either installation. Where can I go to get these basic drivers.
I have tried Logitech with no luck as my kybd/mouse combo doesn't even show up on their site. I have tried going to Microsoft site to get generic 64 bit drivers but they are not being very kind in that regard. There is nothing to download. Clearly they don't want to give anything away free! My Logitech USB kybd/mouse combo is model Y-RK56A for the kybd and M-RR95 for the mouse. My mobo is a Gigabyte GA-880GA-UD3H and I have its CD but w/o mouse I can't get it to install on the Win 7-64 partition. I thought when it installed on my XP partition it would have installed both sets of drivers. Can I extract just the 64 bit USB drivers from there?

Whenever I go to open a tab in Firefox, close a program, highlight my task bar, click anywhere, windows won't register it and I cant do anything. Like other people, the temporary fix is it hit Ctrl+Alt+Delete and the problem goes away, but it always comes back.I recently installed Sw:ToR and I think there seems to be a connection, for this problem hasnt happened to me before, only after I started playing this game. In The Old Republic, sometimes the UI will bug out and whenever I go to highlight a skill or a quickslot button, I was forced to reload the UI by hitting Ctrl+U twice. That would fix the problem in the game. That exact problem that is in this game has somehow made its way onto how my PC works. I can be clicking and highlighting things just fine, but for some reason, it just won't be able to highlight anything that is pinned to my task bar or even click anything there.

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?

My windows operating system is not working properly. It's taking too much time to start. Sometime, after starting, internet connection isn't being connected. After restarting PC it connectes. Sometimes, after starting PC, a message shows that the windows wasn't shut down properly. Then some options come i.e. "Start windows normally" and so on. After pressing 'Enter' it starts.
