Hi,

 

We have iMX53 based board running Linux and for hw reason we want to limit the USB speed to 12Mbit/s (Full speed). I know the EHCI- host controller supports that, but I'm not sure how to do that on Linux side or is that even possible? Is it module option for ehci_hcd module or should it be done via sysfs - interface if only some ports needs to be full speed other high speed?
