Nadler <[email protected]> Still in my review queue -- just so you know. :) Can you remove all calls to usb_ep_buffer_{alloc,free}() in the next iteration? I'll be removing those from the gadget API (they've become superfluous). And in any case, this particular driver doesn't need dma-coherent buffers. No need to repost this driver with just that change, that'd just clutter my queue. - Dave ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
