Hi,
From a usb gadget driver, is it possible to detect whether or not a
usb 1.1/2.0 HOST CONTROLLER? is managing the usb device during
runtime? I want to use different endpoint descriptors based on this
info during the setting up of interfaces.
The USB spec does not allow this, sorry. Please read the documentation
at usb.org for more details.

I think the member 'speed' in 'usb_gadget' structure would do. I'm not
sure if all usb device controller drivers fills this member properly.
But at-least Freescale's driver does it (look at the function
'port_change_irq' in 'fsl_udc_core.c')
