I asked the same question a while back. I was told that it is the driver which is "experimental". I guess it is just a first revision.

Hi All,

The web page describing the Summit expansion board for Overo indicates
that the USB Host port (mini-A connector) is "experimental".

What are the issues here ?

I realize this port is supported in High Speed (480 Mbps) mode only.
Apart from this, are there any gotchas ?  I'm thinking of using an Overo
for a project and a working Host port is essential.

Any good/bad experiences using the Host port fro High Speed bulk
transfers ?
