Hi all,

Thanks Neil. I thought that the switching was manual as per the gta02. Also the gta02 had a powered host mode. Is there is an equivalent on the gta04?

What do you mean by "switching USB modes"?  Do you mean switching between
'host' and 'gadget' mode?

If you do, then you need a USB-OTG cable.  It is a cable with a mini-usb B
plug on one end with the 'id' pin shorted to ground, and a regular USB A
socket on the other end.
When you plug this in, the kernel notices the ID pin is grounds and switches
to host mode.

Something like this
