U-Boot USB discovery get stuck with keyboard or mouse

[guidol]

While U-Boot 1.1.4/3.4.16 is scanning  the USB-Ports and a USB-Keyboard or -Mouse is connected
it wouldnt find my USB-Stick to boot from :-(

When I did start only with the Stick it boots fine. After booting the Keyboad/Mouse are recognized
well and do work.....

Hmm if a Switchable-USB-Hub can solve the problem? I did see serveral USB-Hub with switches coming up
to disable some USB-devices (Green-IT? :-) )

Or will U-Boot 1.1.4/3.4.19 Or .27 do the trick?

The boot process will also get stuck if I connect a LCD2USB Display (for using with LCD4LINUX) additionally to my USB-Boot-Stick :-(
