Due to the fact that on our DM6446 we are stuck, i revert my
investigation on platform DM355. The traces shows that the driver got a
large number of NAK_TIMEOUT events. They can be shown in the tarces
below
Fro mmy knowledge it can come from two reasons:
1/ The peripheral is not ready to receive / send data from/to the host
2/ Some "ill behaved" peripherals always respond NACK to ping request.

Both cases can led in NAK timeout.

To prevent the USB controller from emiting NAK_TIMEOUT on endpoint 0 the
driver writes 0 to the NAKLIMIT0 register. According to user guide:
sprued2c this action should disable NAK_TIMEOUT for end point 0. However
it seems not solving the problem anyway.

I also tried to disable the ping functionality: 
http://linux.omap.com/pipermail/linux-omap-open-source/2007-December/012540.html
But that makes no changes.

So the question is 
- what type of events can issue a NAK timeout on ep0 even when they are
disabled using NAKLIMIT0 ?
- is there a way to disable ping on controle ep0 ?

Thank you all, a lot for your help !
Laurent
