Hello

I am working on an embedded machine that has two USB controllers, one
is a OTG and the other is a pure host.

I have succesfully used g_serial driver on the OTG controller in
device mode and talked to my pc using the cdc-acm driver.
With the g_serial unloaded I have also enabled the ehci-hcd and
cdc-acm drivers and connected the host port to another serial device.

The problem I have now is that I want to be able to have my embedded
machine work as a device on the OTG port and a host on the host port,
but if I load the ehci-hcd driver with g_serial already loaded it
screws everything up since ehci-hcd driver attaches to both the OTG
and the host controller, how can i prevent it from using the OTG
controller?

Best regards
Fredrik Johansson
