Anyway, try rmmoding the hcd modules. That way the USB is de-powered as long the board supports controlling the USB power by software. You can also try with /sys/bus/usb/devices/*/power/level to change the power line for each port separately. But some boards have USB-power hard-wired to +5V_STB, obviously that won't work with these boards. In that unlucky case you can use an intermediate hub and control this hub's power lines. That said: BEWARE FOR CRAPPY USB HUBS! Most of them are. Find a decent one or you'll get even more problems.
