Hi Marek,
I tested on tegra2, Seaboard and didn't see these messages though see
lots of messages
"ERROR: v7_dcache_inval_range - stop address is not aligned -
0x3fb7c608" which are expected.
PFA the logs if you can make out anything useful.
Try to increase the delay in handshake();
Thanks,
Puneet

Dear Puneet Saxena,
This avoids cache-alignment warnings shown in console
when a usb command is entered.
Whenever X bytes of unaligned buffer is invalidated, arm core
invalidates X + Y bytes as per the cache line size and throws
these warnings.

I think we're almost there, hurray! :-)
Though on m28evk this still has issues:

I have a single USB pendrive connected to the board.
Also note, that if I disable the caches, it all works even with your patch
applied. So I suspect there's something even more to this (maybe broken
ehci_invalidate_dcache() ? ). Where did you test these patches?
Thanks!
Best regards,
Marek Vasut
