USB Hub

[Carlosinfl]

Does anyone know if there is a USB 2.0 hub that will power off directly from the usb communication cable rather than have a seperate power cable as well?

I believe most hubs can run like that, but you can't plug any devices into the hub that require more than about 100mA(since you only have 500mA available for the hub+devices).

I've got a USB1.1 Hub that runs off either the cable or the bus power.

I'm sure they make a 2.0 version.

All hubs can get power from the USB cable. However, if you are going to do a 2 hub topology, one of them MUST be powered. Also if you do not use the external power, you may run into some limitaions on the devices working on the hub, usually when you are using all 4 ports.

I usually use only 2 ports and never for more than a few moments with a keydrive.

Shouldn't be an issue then. I typically don't use the external power supply, although I have a few devices that I need to with.
