I have a Y-shaped USB cable, 18" long, with type A at one end and the
two previously most common mini's at the other end, the one that used to
be used for cell phones and the other slightly bigger one.

All 3 ends have the USB logo in the plastic.

Doesn't that mean it's both power and data?

If it were power only, it should not have the logo, right?

Yet when I plug one end into the computer and another end into a Harmony
remote control, I get no beeps from the computer. So that means the
cable is defective, right?


I've had it for years, but I guess I've never used it except for
charging things.

I had a usb external drive that had 1 end plugged into the external usb, and 2 ends that plugged into 2 usb ports on the computer. It
required more power than one usb port could supply. And it was flakey if I didn't plug in both.
