I do not know a reason for that, and it is not supposed to be that way.
On the boards I use I have not seen that behaviour.

The initialisation sequence looks very much alike the Windows/Linux
initialisation sequence these days, there are a few minor differences
but these are valid too and are not related to things like this.
There are still a few weird issues with USB sticks I do not fully
understand yet, but if you can improve it, please provide patches.

Kind regards,

Remy
