Implement USB wifi on MCF52210

Hi, I'm using the MCF52210 demo board which has a USB host, I was wondering how hard it would be to utilize the host in such a way that a USB 802.11 wifi dongle could be attached to transmit data wirelessly. I would imagine a TCP/IP stack would need to be used.

Any guidance would be appreciated.

Thank you

As far as I know, USB 802.11 dongles rely heavily on the host to do much of the processing. It's not "packet sent" and "packet received," there is much more going on in the wireless interface device driver. I think that a TCP/IP stack would be a minor problem compared to the driver. 128Kbytes of ROM and 16Kbytes of RAM might not be enough. And writing the driver code from scratch would be an extremely challenging task. Even getting the USB dongle specs from the manufacturer won't be easy.

Ok, I'll continue to explore other options. Thank you.
