USB individual port power switching

Some USB hubs allow switching of individual ports. This allows USB devices to be totally powered off, and it can even be used to control power to non-USB devices. A web page provides more information and a small program which can switch USB power. It also lists 4 hubs which support this.

Is anyone using a hub which supports this feature? I'm wondering if any of those hubs are compatible with the WL-500W or if there are any other compatible hubs which support this feature.

I'm pretty sure that the WL-500W does not support this on its USB ports because the VT6212 doesn't seem to have registers or pins for this purpose, and I see no other components which could be switching USB power.

I compiled hub-ctrl for Oleg firmware. It requires libusb.

afaik, rt-n16's usb controller supports per-port power feature, but
wl500* don't.
