I just bought a y-cable and it doesn't work on vwii. There's no clicking sound coming from my hdd when I use it (there was before a little) and the power light on the hdd got brighter when the y-cable was used. I have a 320gb WD my Passport hdd, and the y-cable I bought was this one. I think the y-cable is 2.0/2.5, does the vwii only detect usb 3.0?
