i have a z500a too, and the dcu-11 cable, but i cant get it to work
i got it working before, but my comp got all screwed up, so i wiped the drive and reinstalled windows.
ive been trying it for some time now, but it wont work. the computer reads the usb drive, but it cant tell what it is. there are only 2 com ports listed, so i think that has something to do with it
