Nothing under disk management, nothing in device manager. The USB wireless and keyboard/mouse work fine though. Have tried power settings, re-installing USB drivers, rebooting etc. Help please.

I have actuall come into this before on an old laptop I had...... my suggestion is to uninstall windows 8.1(rollback) and reinstall it... its lie when vista had problems with updates. some times you had to install them 3 times before they actually completed.. but 8 just accepts them even if it didn't download right!

the problem is when you let this continue. you will eventually find that your usb root hub under device manager over time will just vanish. and your usb and 3.5mm jacks will quit working altogether... take it from me.. you don't want that to happen.. or maybe you might have something worse... but all I know is once the root hub is gone there is basically nothing you can do =(

give it a rollback but first back up what you need and tell us how it goes... worked fine for me on 1 laptop and 2 friends pc's

generally you would just install the custom USB driver required for your machine. Often many of these machines will have 2 USB chips. one from intel that supports usb 2.x and another from some other manufacture. The intel driver will be supported and detected by the OS but the other one might require a custom driver version. These generally will be on the vendors website for download. Sometimes the only thing wrong is that you need a BIOS update from your vendor to correct settings for the hardware, some usb 3.0 chips made their own extensions to increase speed beyond the standards. These often will not work when a generic driver is installed by windows (unless you turn off the extension in BIOS or get a custom driver installed from the vendor)

Makes sense so I re-installed and upgraded all the drivers for the motherboard from Intel. No luck. Also this is happening on both my new computers, the laptop as well. The old Win 7 machines are working fine with my three USB
HDDs.

I have also had this problem but mine was resolved without re-installing OS first there is an option to download drivers from windows update which for some reason was switched off

firstly open up devices and printers then right click on your machine name... choose device installation settings and make sure that the tick is in the automatically download drivers and realistic icons (forgive me if this is not the correct phrases but its the best that i can remember and it should get you through this section)

after this was done i restarted the machine once rebooted some but not all of the devices were recognized

The next option was to use the tool supplied by Microsoft
http://support.microsoft.com/mats/Windows_USB_diagnosti...

once this completed (it took quite a while as it took an age to install windows powershell) i rebooted and after restart it recognized all of the usb devices

Think my error was error 33 windows could not install this device as it reported an error and just installed them all as standard usb devices

It may help it may not but it is worth a try before re-installation of a full OS

Sorry about the EDIT but i posted the wrong link
