K750i USB problem .

[simox]

First of all install the USB flash driver then restart Windows(if something doesn't works properly restart Windows :D ). If it doesn't helps, try to clean the phone's connector, and use a 'normal' DCU-60 cable. You can try to plug the cable in other USB port(s) too (use the PC's backside USB ports).
