Dear all,

Thanks very much for the information about SDIO.

I will be also interesting to get some information about USB. Is it possible that the Neo1973 act as a USB master in which you could connect USB slave devices? 

Does the hardware support it?
Has the software been tested for this feature?

GTA01 can support SDIO on the microSD connector (although the current
kernel image does not yet contain the linux SDIO stack.  Work on this is
happening in the mainline kernel, and we will leverage this as soon as
it appears in mainline 2.6.x)

GTA02 cannot support SDIO on the microSD connector.  This is due to the
fact that the samsung s3c24xx itnernal SDIO compliant SD controller was
used to attach the internal WiFi module.  The controller we use for the
microSD slot/card is MMC/SD only, and does not support SDIO.
