All of a sudden usb ports quit working

usb ports quite working. There does not seem to be anything in them. Any ideas.

A reboot is the first logical step.
Try resetting PRAM, it will reset the Serial Port Configuration and Port definition

Usb ports quit working?

I am using VM virtual box to run windows xp on a windows 7 (64 bit). I have rockwell rs logix installed on the windows xp. I had created a virtual drive to share my old files and set up a usb port to run a usb to serial adapter. I set the serial port up in the vm software and everything ran great. Then I got a notice for a new version of VM and now I can not get it to use the usb ports. I have gone through and uninstalled the vm software and re-installed it re did all of the parameters as before and still it will not use the usb ports. Here is the code that I get
It fails to attach the usb device unknown device to the virtual machine.
Result code: E_invalidarg (0x800070057)
Any idea what changed or how to change it back?
I have tried plugging in other usb items and they will not work either.

Hello! There have been reported problems with the mouse cable fraying at the end and thus not working but if the ports themselves aren't working try unplugging everything including the 115 volt power cord to the wall and letting it sit for 30 minutes and then restarting. This allows the ports to "reset" . Tom

Keyboard USB port quit working

My wife's G4 has my G5 keyboard attached. She recently unplugged a USB device and now one of the two USB ports on the keyboard doesn't function. Anyone know how to re-boot that port?
G4 PowerMac Mac OS X (10.4.6)

What kind of USB device did she unplug from the keyboard? Was it something self-powered or did it draw its power from the USB port?
PowerMac G5 Mac OS X (10.4.6) 1GB RAM, nvidia 6800 ultra, Apple 30" Cinema Display

All usb ports not working

All of a sudden ALL (front and rear) USB port are not working my G5 1.8
When I turn on the computer I get to the log on screen and natuarally I cannot
use my mouse or keyboard.
Is there anything I can try to reset the ports?
Also, is there any way to foce the computer to boot from the restore CD
without having the use of the "C" key on the keyboard to do this.
Any help would be greatly apprecaited.

Hi Tom,
Thanks for your help. I unplugged the power from the computer and even took out the internal battery and let it sit overnight. It still did not work.
I took the computer to the nearby Apple store today for repair. I was told that most likely the motherboard would have to be replaced at a cost of about $600.00!!!!!!!!
Then I was told that I should get a USB PCI card. I never thought of that.
That did the trick. My computer is working fine via the PCI card.
Thanks again for your help.

HP Pavilion dv6 All 4 USB ports stopped working

Hello,
I recently bought a Pavilion dv6-6c11sa laptop. Windows 7 Home Premium 64-bit
Everything was working fine for about a week, and then yesterday all of the USB ports stopped working. I have 4 USB ports in total, two 2.0 and two 3.0. No matter what peripheral device I plug in, mouse or flash drive etc, they're not recognized by the laptop. The lights don't even light up on the devices, regardless of the port. I've tried uninstalling and reinstalling the drivers in device manager, taking out the battery and rebooting, installing the chipset drivers (AMD), nothing works. No programs had been installed 3 days prior to the occurence, although I had rebooted several times in that time frame. I simply booted up the laptop yesterday, and nothing worked.
Could anyone offer a solution or suggestion, please?

Hi,
What about if you try to install drivers from your product's page?
http://uk.msi.com/support/mb/Z97-GAMING-5.html#down-driver
And when exactly it starts to fail to work? Did you try to have OS just installed, restart it and see if it works then? Are you able to determine which driver installation causes USBs to stop working?
thank you
i just remove USB3 controller driver and work
thank you all :D

Thinkpad W530 Yellow (Rear) USB port stopped working

I have had my W530 for about 3 month and the rear yellow USB port just stopped working a few days ago. I have recovered the whole system to factory status and updated the BIOS but the USB port is still not working. I tried several devices, it seems like that the USB has no power at all. The LED on the flash drives do not come on when I plug it in. All the other USB ports are working. Has anyone encountered the same problem before? Any help is appreciated.

Hi all,
The yellow USB port of my W530 stopped working suddenly today. It can charge but cant recognize any devices. The other devices work well. I have tried many ways like updating the bios, setting the bios to defaults... still not working.
seems that its a big issue
Any ideas? Thank you!

USB ports not working after OSX 10.9.1 update

I have a late 2011 MBA 13".
The 2 USB ports stopped working as soon as I updated to 10.9.1.
I tried zapping PRAM and resetting the SMC.
I even turned the thing off for hours and still nothing.
Any idea how to fix?
Everything was fine until I did the update.
Thanks.

This is not a known bug affecting 2011 MBA computers with 10.9.1 so there is something wrong with your installation. Since zapping PRAM and resetting the SMC did not work I suggest that you try one of two things but first make sure you have backed up your computer.
1) download Mavericks and reinstall it. Sometimes an update goes awry and a reinstall fixes it. Since doing this won't disturb any of your data or applications it would be my first choice. You'll be downloading 10.9.1 so you won't have to perform any updates.
2) boot into the recovery mode, erase the hard drive and then download and install Mavericks. Once Mavericks is finished installing you'll be asked if you'd like to migrate data and applications from a backup. Say yes and if your backup drive isn't already connect it, do so. Select your applications folder and account folders from the list and let the Setup Manager do its magic.
BTW - this is why one of my several backup hard drives is a cloned backup using Carbon Copy Cloner (SuperDuper! Is another good choice). I can boot up my computer using this backup and download the newest version of Mavericks on it if I haven't already done so. I always quit the installer first and make a copy of it because the installer program deletes itself once it is finished which is something of a pain. It gives me more options including being able to boot my computer with it, erase the computer and copy the installer to the computer rather than having to perform the download all over again if step 1 fails. Since I always download a new copy of the OS when Apple releases an update this computer will have the newest version of the installer so I also can skip the download step of option 1 and just copy it over and install on the computer.

I have a Pavillion dvd Model 1245dx. USB ports stopped working. How can I fix this?

My USB ports stopped working. So did my DVD drive. Any ideas how to fix this?

Back up all data before proceeding.
Step 1
From the menu bar, select
           ▹ System Preferences... ▹ Date & Time ▹ Time Zone
Check the box marked
          Set time zone automatically using current location
if it's not already checked. If the box is checked, uncheck it and then check it again. Test.
If the correct location and time zone aren't shown in the preference pane, then either Wi-Fi is turned off, or you're not within range of a network in the Location Services database. Under those conditions, the computer can't determine your location.
Credit for this idea to ASC member Easyas314.
Step 2
Triple-click anywhere in the line below on this page to select it:
~/Library/Containers/com.apple.Maps
Right-click or control-click the line and select
         Services ▹ Reveal in Finder
from the contextual menu.* A Finder window should open with a folder named "com.apple.Maps" selected. Quit the application if it's running. Move the folder to the Desktop, leaving the window open. Relaunch the application and test. If there's no change, quit again and put the item you moved back where it was, overwriting the one that may have been created in its place. Otherwise, delete the folder you moved. The list of recent places displayed in Maps will be lost.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

IMac (Mid-2007) USB Ports Not Working

So all of a sudden my iMac (Mid-2007) USB ports stopped working.
I turn on the iMac and it boots up. I can see desktop. I see the cursor in the upper left hand corner. I tried to use my Apple keyboard and mouse and nothing moves. I tried several different keyboards and mice and still the problem persists. I shut down and reboot it restarts and the same problem.
I've read several posts on the Internet stating it could be a power supply issue. If it was PSU why does it even start up. If its logic board thats an expensive repair as I've already looked around for logic board replacements. I wouldn't even know what Apple would charge to fix this issue.
Can somebody help with this issue?

Reset the SMC > Resetting the System Management Controller (SMC) only wait for a few minutes in step three instead of 15 seconds.
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds. <---- Wait a few minutes.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
Then if that doesn't reset the USB port overload protection, go to > Apple - Find Locations and contact your local AASP to get an estimate.

Installed Windows & 32 Bit But Drivers and USB ports NOT WORKING.

I bugh an HP Pavillion TS 14 Notebook that came preinstall with Windows 8.1 64 bit which I hate so wiped the drives and installed Windows 7 32 bit and now I have a big problem. None of my network drivers work and the 2 uSB ports where I plug my mouse and other SB hardware in no longer work.
I did a back up of the SW Set up file that has all of the HP dvers for my laptop but both the network and video divers won't install. And When I try to install the drives I get the eror message saying they are not compatible with this version of Windows.
I have loked on the HP website under my laptop model which s as above but HP don't do drivers for Windows 7 32 for my laptop. And I have looked on both the Realteck website for both the Realteck ethnet and Realteck wireless network drivers but none of them work or install on my operating system. The video drivers Intel don't work either. So I am really stuck a I cannot go back to Windows 8.1 as though that 32 bit Windows 7 would work on my laptop but most of my drivers are not compatible with the operating sytem And I don't want to install 64 bit Windows as I like 32 bit.
The drivers that are not working on Windows 7 32 bit are:
Realteck RTL8188EE 802-11b/gn witeless lan
Realteck ethnet die and
Intel High definition graphcs driver
Which don't work at all on Windows 7 32 bit as they are 64 bit only drivers.
So can you please post me a link bth the network and Intel graphics drvers that work with my laptop. As I have tried lots of different Realteck and raphics drivers for Window 7 but NONE of them work on my system. And None of my USB ports are working either. So how do I solve this problem?
This question was solved.

Hi:
Should be no problem to get W7 32 bit to work on that model.
Just use all of the drivers and software from the HP Probook 450 G0 on your model except the Audio, BIOS and firmware files.
Your model uses the Intel HD graphics driver only.
The first driver you have to install is the Intel chipset installation utility and then reboot.

Audio: Accept the agreement. Download and install the first driver on the list.
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=24&Level=4&Conn=3&DownT...
If for some reason, the Intel HD graphics driver from that model does not work, then use this one...

Cannot get USB port to work after re-installing of SP2 on Satellite Pro L20

After re-installing XP Home SP2 and downloading all the updates & Drivers from here I cannot get my USB port to work properly, if I have more than one peripheral plugged in it says "Bandwidth Exceeded".
I have a Behringer BCD2000 which is a souncard/midi controler for DJ mixing, it worked fine before i reinstalled windows, now it clicks and pops when playing tunes, also the ASIO doesn't work when I run Traktor (Dj software) and the program freezes. Any other external sound card wont work either. I've been all through the device manager no conflicts apart from an ! over Serial under hidden devices.
I'm lost, is my only option buying a PCMCIA sound card, it worked fine before so surely there is a software solution to this?
If anyone can help I'd be most appreciative.

Hello
Try to disable USB Error Detection:
1. Right-click My Computer and then click Properties.
2. Select Device Manager to view the Device Manager
3. Locate and click the Universal Serial Bus Controller entry.
4. Double-click Universal Host Controller and then click the Advanced tab of the Universal Host Controller Properties.
5. Put a checkmark in the box for Disable USB Error Detection. Click OK.
6. Restart the computer to see if "Bandwidth Exceeded" message occurs again
Did you use recovery media to reinstall WXP? When someone write it worked before and now not it is really not easy to say why this happen. Try to configure notebook as before and maybe it will work again. Behringer BCD2000 is not known to me and I dont know how it works and which software must be preinstalled there.
Can you use different USB devices like external HDD, USB mouse, USB memory stick or printer?

USB ports not working in safe mode

I am trying to back up my computer before i take it to the apple store and i cant back up in safe mode using time machine, becuase im guess the USB ports arent working. Are there any solutions to this problem?

Ok, where is this Intel driver? There is no such thing "program manager" so I am guessing you mean the Programs and features control panel, but on my machine that whole window is blank after a clean install. I still cannot get the USB ports to activate. Two fresh installs and several different USB sticks later and no luck. Should I just give up and go to Windows 8.1? I really need Windows 7 to work if at all possible. Other devices shows one USB controller without driver software so I suppose that's the culprit. There are other USB devices installed under the USB section of Device Manager, but they apparently have nothing to do with the USB ports themselves, just devices like the trackpad etc. I've spent two hours on this so far and it's getting out of control. Why doesn't this work with generic USB drivers?

USB ports stopped working in my Macbook Pro

USB ports stopped working in my Macbook Pro

I do not know anything about audio consoles nor do I have an iPhone.
My iPod also does not show on the desktop but it is recognized in iTunes, Check if that is the case for your MBP.
Do you have the appropriate boxes checked in Finder Preferences?
See if this support article is of any assistance:
http://support.apple.com/kb/TS1410
If you have an external HDD, connect it to your MBP and see if it is recognized. If it does not show on the desktop, check Disk Utility.
Have you tried all USB ports? It could be that the problem lies in your MBP.
Ciao.

MAC PRO Internal USB ports stopped working

Hello, I have a mac pro 8 core with an USB internal ports problem, the 2 in front are not working anymore, and from the 3 in the back only the middle one is working.
I tried to pull all the power out for a whole night, resetting the pram and nvram but nothing helps.
When for example I put in a keyboard in one of the ports that is not working and when I power up the machine and I press the ALT key I get the choice of startup preferences, once I select one, and the system boots up the ports stops working, so before the OS loads the usb ports are working !!!
What to do ??

This is a hardware failure. While USB ports on the whole are just not designed very well, leading to their failures being pretty common, your issue sounds a bit more like the USB controller chip is failing.
In any case, the answer is to take it to a repair shop. If they're smart about it, they'll replace the logic board and see if that also fixes the front ports. If not, they'll replace the front I/O panel as well.
