Impossible to find missing driver for Unknown Device in SVF1532E4E Hello, can anyone advise on how to find driver (Windows 10), for an unknown device in Sony Vaio laptop SVF1532E4E (or SVF153B1YM). I've tried Windows updates, Sony's website, programs like Driver Booster or Driver Update, searching it by the hardware's ID - no luck.
