Windows 7: Keyboard problem

Switch off USB2 setting in the Bios menu > reboot
Then switch on again > reboot

In fact make sure usb settings haven't reset somehow in the bios - some can actually turn off certain usb keyboards? on default! I have seen an Asus A7N8X-E do this!
Test


If that doesn't work - try pulling out the Electric lead from your PSU for 2 Minutes.

Then plug back into electricity/switch back on

You must remove the lead completely from either the wall (for two minutes) or the PSU socket - it resets USB chip on motherboard.

thanks for trying to help.
Scroll right to the bottom of "device manager" click on
> "Universal Serial Bus Controllers"

Hub a lovely time!

Tell me how many 'controllers' you have in there please & is "standard enhanced pci-usb host controller" in there?

Here is my device manager.
If the keyboard doesn't working well, theres a error sign on the USB input device and the Keyboard on the device manager is not there.

I saw USB Legacy support, it has a description and (keyboard and mouse support?)

btw, I cannot tell if it works or not, because I already reinstall the driver, the keyboard will work fine even if I reboot. ^_^

Thanks for posting back that you are up and running!

Hopefully resetting the USB chip allowed the keyboard to be seen properly again and the driver to load properly!

sad to say, it's still the same.
but when I check the problem, I've read about some damage/conflict in the registry.. something like that.
sorry I forgot to have a picture.

Just saw your new post in user CP!
Taken off an MS Tech-support site try this >

Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall all devices under Storage Volumes.
Say no to any reboot prompts until you are finished.
Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

If that fails try a different usb keyboard!
