What is "PCV-W2"? eg: a pcmcia audio card, a notebook model, other? please specify.
Open Device Manager, find and double-click the PCMCIA device, click the Details tab, select "hardware id" and give me the hardware id string that begins with "PCMCIA\xxxxx", (1st./top line of text only).
What exactly do you mean by "Sony downloads useless"? And please loose the caps lock key when posting.
