Does that mean that if buflen is multiple of wMaxPacketSize, the UDC driver should fit as many [DATA] packets into one usb_request and call complete() or it will always call complete() on each [DATA] packet, thus not requiring buflen at all? Does that mean that we can still use buflen and this patch is still valid? (besides the endianess issue that was addressed on v2) -- Felipe
