I'm trying to force a host to re-enumerate our device from the linux

access to the cable in the completed system.
Often the solution is to add a vendor specific command to force
the slave device to soft-detach from the bus (eg: disable the usb
module and then enable it again) and then it will be
enumerated again. You can even force the reset of the whole
slave device if you want.
That's not the issue here. Marc's problem is that he doesn't know
_how_ to force the slave device to soft-detach from the bus. None of
the things he has tried so far have worked (but I don't think he has
tried rebooting the device).
Thanks, yes we've tried rebooting. The reason we have this issue is that
after rebooting the device, the host does not recover it's networking
over g_ether/RNDIS.
