After restoring from Windows 8 upgrade, I have noticed that Windows Device Manager could not initialize previously working devices. I have tried to reinstall USB controllers and things went from bad to worst. Now keyboard and mouse are not recognized, so I'm left with a pretty useless system.
- I have tried to use other USB mouse that working with my laptop, but nothing has changed.
- Tried to connect wired mouse via PS2 adapter, no luck system is not recognizing it.
- Launched Ubuntu from USB stick, all working fine, (Currently using it)
- Tried to insert Windows 7 installation disk, repair option does not fix anything, but I'm able to launch command prompt.
What's interesting that for few minutes before login screen mouse is working so I have just enough time to launch assistance and call virtual keyboard, after that it's unresponsive again.
I'm running out of options and would like to know is anything else could be done with current options, apart from buying new appliance or completely reinstalling windows 7?
