I've got a G4 Cube, which has two USB ports and no way to add more. And I've apparently got some problems with my USB devices getting enough power, and I can't figure out what I can do about it.
The USB devices I need to connect are:
- my keyboard
- my mouse
- my TView Micro VGA->S-Video adapter, so I can hook the Cube to my TV (it draws power from USB)
- my Griffin iMic USB audio adapter, so I can hook the Cube to my speakers (the Cube has no audio output)
- my new EMS USB Playstation controller adapter
I have a four-port Belkin USB hub, and an eight-port no-name USB hub. Both are powered via a wall plug.
The video adapter and the EMS Playstation adapter both seem to need to be plugged directly into the Cube. If I plug one of them into either of the USB hubs instead, it won't work at all. The eight-port USB hub has a green LED for each port, and when I plug either of these devices into it, the green LED for that port goes out until I cycle power to the hub.
I can't figure this out because a powered USB hub is supposed to be just as good as the USB port on the computer itself, right? Are some hubs better at distributing power than others?
And if I plug both finicky devices directly into the Cube, then of course I can't connect any other USB devices to it.
Am I hosed, should I not be using a Cube for this?
