Usb Ports On Toshiba Laptop Are Not Working

the usb ports on my Toshiba laptop are not working.


Both USB Ports On Laptop Suddenly Stopped Working?

Aug 12, 2011

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.

USB Ports Stop Working When Laptop Moved To Another Location

Jan 31, 2012

Toshiba Satellite A665. My USB ports work fine from startup, and can even work after waking from sleep mode. However, I notice that if I move my laptop to another location, my USB gets disabled. Occasionally, my mouse and other devices may receive power, but other times they may not even receive power. Either way, they are never detected anymore. I have already tried unplugging and replugging the devices to no avail, and I have also reinstalled all of the drivers.

I love this laptop for it is the only one out there that I found that has a lock for the touchpad.

USB Ports Not Working At All?

Jul 3, 2012

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.

Usb Ports Not Working?

Apr 22, 2012

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?

Usb Ports Not Working On Windows 7?

Mar 19, 2011

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.

All USB Ports Stopped Working?

Feb 8, 2012

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.

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

USB Ports Not Working In Windows

Apr 18, 2011

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.

HP DV7-7135US - USB 3.0 Ports Not Working At All

Dec 29, 2012

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%.

Upgraded From XP To Windows 7 And Now USB Ports Not Working?

Jun 20, 2011

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

Product Nameze2108wm
US Product NumberEA390UA#ABA
Microprocessor1.6GHz AMD Mobile Sempron™ Processor 2800+ with PowerNow!™ Technology
Microprocessor Cache256KB L2 Cache


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 =/ )?

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?

Usb Ports Completely Stoped Working

Feb 20, 2009

Not to long ago i had downloaded and installed windows 7 beta to my hp elite desktop and it seemed to work very good it was slightly faster than vista which was on it before but im also a gamer and have about 4 games on it and usually play with my 360 controller thruogh the usb port. Well while it was installing the driver for the controller it all the sudden stoped and said usb device unpluged so i jus said whatever and jus treid to use the keyboard and mouse but noticed my keyboard wasnt working so now i was thinkin great what now.

I tried all the usual things to get it to work even unistalling all the usb ports then restartin to let them reinstall to actually payin $40 for a pci usb card witch none of these things worked not even the new card witch was very agrivating cos it seemed to work for a few other people on some different forums. So my next step was to contact microsoft and let them know what my situation was and well they said they werent responsible for it and duh like i didnt know im the one that chose to install it this person acted like i was blaming them when all i asked was if there was a way to resolve my problem like maybe an update or somethin and thats the only thing i got from that dumb fckr witch was retarded.

so i sent another email sayin the same thing and a different person told me to look at the forums and said there most likely is a solution around but without finding one i decided to post this and i am new to this so forgive me if this is the wrong area for this post im also new to computers all i want is my pc to work good again i had to buy this dell labtop jus to find a solution because my internet is thruogh a usb modem.

And i forgot to add not one usb port works all of them in the device manager have the exclimation sighn.

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

Dell Inspiron USB Ports (Two Of Four) Not Working

I have four ports. Two are working, and other other two are not. My Logitech unifier is recognized and also the cable to and my printer. Flash drives are not at these two ports, but if I remove the unifier and plug in a drive, the drive is recognized. I ran Dell's "USB Status Test" with the pre-installed software, and both "pass the test"

USB version 2.0.0
Microsoft driver version 6.1.7601.21692, 6-21-2006

USB And Disc Drive Ports Not Working

Aug 17, 2011

All of a sudden about two weeks ago one of my ports for my wireless router dongle decided to quite so I used another and after a couple days that quit as well. Now none of the four work nor does the disc drive. I have tried everything to attempt to correct this but I get the same result. I don't know if it is in the system configuration I am missing or the CPU board going bad. I would hate to buy a new board and have the same results their by telling me it was the Windows 7 software all together. I could re-install Windows 7 but I do not want to delete all my programs I use that are loaded.

USB Malfunction / Ports Stop Working

Dec 31, 2009

i have a problem with my USB under windows 7 64 bit. Whenever i seem to do any intense activity that is using USB the USB ports stop working. When i say intense activity, i mean copying over a large file to a jump drive or external drive, burning a DVD on external DVD drive, etc. My game controllers, mouse, and Mic headset all work fine and don't cause the USB to malfunction.

Any help would be greatly appreciated, thanks. i have reinstalled my motherboard drivers and aside from that i have no clue what else to do. I did not have this problem under XP.

USB Ports Stopped Working - Windows 7?

Apr 27, 2012

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.
