Downgrade to the previous version did not help...

Could it be a power supply problem?

When I insert a mous to the right USB port the light appears but nothing happens when it is inserted in the left one...

Left side USB is on a separate, audio card.  I would guess the problrm is hardware.  Either the ribbon cable is unplugged or the audio card died.  See if the headphone jack works.
