Feature Description

Hello, my question is if we can force somehow ehci-platform on USB2.0?

op5plus@op5plus:~$ lsusb -t
/:  Bus 001.Port 001: Dev 001, Class=root_hub, Driver=xhci-hcd/1p, 480M
    |__ Port 001: Dev 002, If 0, Class=Hub, Driver=hub/4p, 480M

I realised that depend on device it can be on ehci or ohci platform. This changes the BUS number even if I plug two devices into one port one by one.

I need to create udev rules for alias for specific physical port. It's not a problem in USB 3.0 because there is only one driver.
