Suddenly all USB ports stopped working on win 7

[rijans]

That day suddenly my PC's USB ports stopped working. I tried all USB ports with deferent kinds of drives(pendirve, mobile, modem) but computer is not responding. I tried reinstalling my windows 7 but remains same. I also tried Ubuntu, Mint, Hirens Boot CD etc but no OS finds my any kind of USB disc. On windows 7 I tried uninstalling and installing USB drives manually but don't work. In the mean time today at dawn one of my USB modem started working(on Win7) but after some seconds it became like before.

Can anyone figure out which problem I'm facing? Is it related to my hardware?

First place I would start would be update all primary drivers for your PC, what ever flavor you have, desktop/laptop. Go to that vendors website and download and install all the latest drivers. If you have add on specific hardware go to that vendors site for drivers.

The next thing I would do is to rule out any Virus's, malware, spyware and adware that my be lurking about your system. It's known that some of these nasties can and do corrupt system software and hardware.

Boot into safe mode with networking and then update anti-virus and malware, run a complete anti-virus and malware sweep, see what comes up and report back.

Unplug the PC from the power cord. After it is unplugged, hold in the power button for 30 seconds or so. Leave it unplugged for approx. 1/2 an hour. Try it again. May not be the fix, but it easy to try and it can work when it is not hardware related. A Guy

I had the same problem (all of a sudden).

I expanded "Universal Serial Bus Controllers" branch in the device manager. My USB Root Hubs were showing warning symbol.

I just right clicked each of them, chose "Update Driver Software" and in the popup, chose "Search automatically for updated driver software".

Now the warning symbol in my USB Root Hubs disappeared and devices work without any issue.

I am currently having this exact problem, except there is one USB port still working (which I am constantly having to alternate between my keyboard and mouse). I have two forward USB Ports which still deliver power as my keyboard numlock indicator lights up, but it doesn't receive any data signal.

Device Manager shows an "Unknown Device" in the USB Controllers group, with a yellow triangle around an exclamation point. Somehow, despite that windows doesn't know what it is, it is able to tell me all drivers are up to date for this device.

The problem started just a few minutes ago when I booted my computer, it had been shut down normally about two hours prior. Upon logging into Windows the gadget in the corner of my screen showed an unusual spike in processor usage going up to 45-55% when it's normally around 10% or less at that point in the start up. I was also alerted that new drivers were unable to be installed.

I rebooted and that same scenario played out with no change in the circumstances. I am currently running Ad Aware and Malware Bytes to see if there's a problem there.

Assuming you have tried all of the above (the unlug one will surprise you, it can work )

You say, "I was also alerted that new drivers were unable to be installed." Is this when trying to update them yourself, or that was a popup message unrelated to you trying to update?

1st thing is easiest. Pick a restore point from before this began, and see if that corrects the issue

If no help, you can try uninstalling the drivers and reboot and windows will find them for you.

Open Device Manager> Right click the USB controller and choose Uninstall> Agree when it asks you if you want to proceed> Repeat for all USB controllers> Reboot, Windows should find and install drivers from the Driver Store

See if that works.

Actually, I didn't try any of that. Whenever I find a problem that I don't think I can solve, I do not even bother trying to work it out or find a solution. I immediately ask someone, or a group, that has demonstrated knowledge of whatever the issue involves and the problem fixes itself before they can open their mouths. This method has worked yet again.

I have no idea what the problem was, it was a pain in the butt to log in here and type and post while having to switch the keyboard and mouse out, but when I was done with that I rebooted again (which didn't solve the problem the first time) and it works now.

I found out recently (Monday) that loading Topo and Street Maps from DeLorme hosed my USB Ports and disabled my Veris IR panel (USB driven). Seems the software grabs all the ports looking for a GPS when I selected Sync. It wouldn't talk to my older Earthmate PN-20 GPS. That crap got removed in a hurry and after a reboot, everything was fine. Oh yeah, one other thing the software did was to hook my video driver. When I closed the Maps, I saw my video options panel disappear right behind it. Creepy software for sure.

Just saying; Have you installed any type of USB polling software lately?

Well if it was a pain in your butt just imagine how we feel !

I am currently having this exact problem, except there is one USB port still working

Hey! I just created an account to maybe help some people who stumble upon this discussion (like I did) when searching for a solution to this problem!

I just managed to solve it this way:

1. Go to Control Panel -> Device Manager
2. Locate Universal Serial Bus controllers (USB)
3. Right-click it. (There is no need to expand the branch.)
4. Select Scan for hardware changes

All done!


(I might add that when I tried unplugging my computer, holding the power button a while and removing the "motherboard battery" for half an hour, the weirdest thing happened: The USB-port that was working changed to another one. So it took a while before I could figure out how to get back into the computer; if you're in this situation, just try to locate the USB-port that does work, and use your mouse/keyboard as needed.)

All USB ports died simultaneously

Same problem - all my USB ports are dead. I cannot use a keyboard or mouse, so I cannot do anything listed, other than the push the power button and wait technique. I don't get any messages and I do not get the three beeps on startup to indicate keyboard malfunction. Any ideas where I can go next? Haven't pulled the side panel to check the mb or the ports themselves.

USB ports not working

Thank you, A Guy.

I did not unplug my laptop but I did hold down the power button for 30 seconds and stayed powered off for 24 hours. When I rebooted all of my USB ports are now working properly. Prior to doing this, however, I did make sure my Windows Update was current.

Again, thank you it was the last attempt I tried after trying numerous things.

For me the newest Citrix receiver was the cause

Just in case ....

After a clean W7 install and subsequent installation of several apps I also encountered the sudden stop of all USB ports and subsequent freeze on shutdown.

After reading numerous threads about this subject on this forum and other forums I found that none of the solutions were working for me.

I went back to another clean install of W7 and then tested this problem after installation of my programs one by one. I found that the newest version of Citrix Receiver (version 4.3) was the cause. Then I went back to version 4.2 (december 2014, still available on https://www.citrix.nl/downloads/citrix-receiver.html) and the problem was gone.....

Deinstallation of 4.3 and reinstallation of 4.2 didn't work, I had to go back to a recovery point before the installation of 4.3 and then do the installation of 4.2.

Just in case this information could help others...

A happy Dirk

SplitCam was the culprit

As this was the first thread that listed on Google search, I'm posting despite its age.

This just happened to me following switch-on some hours ago.
My motherboard only has one PS/2 port which is normally used by the keyboard - my everyday mice are wireless USB. I do have a spare PS/2 mouse, so I had to use that and continually swap mouse/keyboard, rebooting each time to have the devices recognised. Tedious.
After trying all of my three USB wireless mice and another USB cable, and testing all on my second machine (they all worked), I looked elsewhere. Under Device Manager, all USB entries bore the yellow exclamation mark. ALSO, so did two SplitCam device entries. AHA! Prior to switching off I had followed my normal practice of running Autoruns.exe and unticking all the usual unnecessaries stopping them from running at Startup - updaters, helpers, keyloggers; crap from many, including Crap Cleaner, (which is a bit of a joke). This clean included unnecessary SplitCam entries - I never used it after the first test run, and why would you want anything like that to start at boot? You use it when you use it! Well, I ran IOBit Uninstaller to get shut of SplitCam, and its deep scan found hundreds of leftovers, AS DID I, later, in various Windows directories, and tons in the Registry. It had insinuated itself EVERYWHERE - in all Registry entries for both Audio and Video, drivers, codecs, facilities, everything. It took me ages to delete them all.
It also took me ages to get back into Windows. Repair failed every time, Safe Mode never happened, it just kept rebooting. Sadly, I can't remember what I did to get back into Windows, but when I did I searched Computer and Registry for remnants, and, as I said, found absolutely tons. I deleted everything I came across.
My PC may not boot when I next try, or perhaps all the USB ports will disappear again. However, wiping each and every occurrence of that piece of nasty awfulness gave me sufficient pleasure that I don't mind if I'm forced to reinstall Windows. I really hate SplitCam right now - remember the name, and steer well clear. Or at least don't stop it Starting at boot or it'll throw a hissyfit and take out all of your USB ports with it. Shame on you SplitCam. If you weren't being malicious then you need to find better programmers. If I was rich, I'd sue you for the trouble you caused, and may yet cause, as I still have to switch off for the night.
