Vanilla 3.4.38: USB devices init takes a long time

Hello,

Currently I'm working with vanilla 3.4.38 on x86.
Before getting the busybox prompt, it seems linux has a long step handling the USB devices.

If there is a USB keyboard connected, it adds 10(!!!) seconds before getting the prompt.

In case there is also USB DVD and USB disk is adds 30(!!!) seconds before getting the prompt.

I configured the kerenl with the default settings.

When I worked with 2.6.27.35 I did not have this delay.

Can you help ?

Thanks,
Zvika
