  467. to single and multifunction SDIO cards.
  468. Some SDIO cards will need a firmware file to be loaded and
  469. sent to VUB300 chip in order to achieve better data throughput.
  470. Download these "Offload Pseudocode" from Elan Digital Systems'
  471. web-site http://www.elandigitalsystems.com/support/downloads.php
  472. and put them in /lib/firmware. Note that without these additional
