dual boot: Win7+Ubuntu 11.10 - usb mouse+keyb not working at installing and in Ubuntu

Asked by pae hoo on 2011-12-12

I use windows 7 64bit for a while and everything works fine. Now I'd like to start using ubuntu 11.10. So I installed it on a different HD. But I cant use USB mouse and keyboard. USB does not working right from the beginning of installing, so I installed Ubuntu with an PS/2 keyboard. PS/2 mouse does also not work.
Is the problem caused by motherboard? its GIGABYTE GA-890XA-UD3.
Any ideas what I can do to solve the problem? I dont want to start Ubuntu out of Windows7, I want to install Ubuntu on a different HD.
Thanks for helping!

Have you checked in Additional Drivers? There might be some missing drivers.

Make sure that "Legacy USB support" option was turned on in the BIOS settings

Plase, boot from a LiveCD, open a Terminal and type in xev. A new window should pop-up. Then, test your keyboard and mouse there. When finished, close the window. Does it works in the LiveCD?

Thank you all for helping!
Its working now!
I tried answer 2, from marcobra.
Legacy USB support was already on. So I checked for other USB information.
'USB Mouse Support' (in 'Integrated Peripherals') was disabled, so I turned it on and it worked.
Then I turned off, to check, and it also worked!
Then I started Win7, made a restart from Win7 and opened Ubuntu. Result: Did not work.
Now I remember, that same thing happened when I had dual-boot Win7+XP.
Ok, now I know how to do. I only wonder, why USB Mouse and Keyboard did not work when installing Ubuntu from CD.
Ps: I wanted to Install from USB-Stick, but did not work.

Thanks again!

When you installed Ubuntu, you could have downloaded drivers for your mouse and keyboard. The CD can't hold all the drivers for all imaginable hardware.
