Are you sure? I haven't come across this meaning yet.

But anyway in kernel full speed realy means 12Mbps. Looks like 
g_file_storage can handle USB 2.0 (CONFIG_USB_GADGET_DUALSPEED) but it 
is not enabled.

It looks like the host mode is only 1.1 (there is only ohci-omap, not 
ehci) but can at least the client/OTG mode do USB 2.0? Or is 'USB 2.0 
device mode for PC connectivity' here http://europe.nokia.com/A4145105 a 
mistake?
