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.
