USB host controllers follow one of two standards : UHCI ( Universal Host Controller Interface(HCI) ) or OHCI ( Open Host Controller Interface(HCI) ). USB主机控制器遵循两个标准之一:UHCI(通用主机控制器接口)或OHCI(开放式主机控制器接口)。
For Bluetooth, the Host Controller Interface(HCI) ( HCI ) driver packages the higher level components to communicate with the hardware. 对于蓝牙设备,主机控制接口驱动包含了高层硬件通信组建。
OHCI Open Host Controller Interface(HCI) 开放式主控制器接口(HCI)
