In reply to tfitz:
I don’t think I made it clear that the lower component cannot use xHCI_usb_env_cfg in its “get”. The lower component does not know the name of the config object is xHCI_usb_env_cfg. Basically, there are two ENV’s that use the same lower components as well as the same config class usb_env_config. One ENV calls the config object xHCI_usb_env_cfg and the other one calls it BDCI_usb_env_cfg.
