Hi Robert,

When I trace the s3c-gadget driver, I found that the driver did not use
DMA mode because of the 32bit align problem. Have you solved this
problem ? I think just do one more time copy when meet the unalign
buffer address can make the DMA mode work correctly. Does any body have
more suggestions on this issue?
