Host Controller Driver Selection

This section explains the selection options for the USB Host Controller Driver layer. The options are set in the file usb_config.c.

The USB Host Controller Selection options enable the host core to determine which USB Host controller driver to use.

Custom EHCI for NXP Devices USB Host Controller

Select Custom EHCI for NXP Devices as Controller Interface if USB Host is Custom EHCI for NXP Devices compliant.

RL-USB Host Select Custom EHCI

OHCI USB Host Controller

Select OHCI as Controller Interface if USB Host is OHCI compliant.

RL-USB Host Select OHCI

Custom USB Host Controller

Select Custom as Controller Interface if USB Host is Custom (non-OHCI/EHCI compliant).

RL-USB Host Select Custom

Controller Interface for Host 0 selects USB Host 0 Controller Interface. This options corresponds to #define USBH0_HC_IF.

#define USBH0_HC_IF                   1                   // 0 = custom, 1 = OHCI, 2 = NXP EHCI

Controller Interface for Host 1 selects USB Host 1 Controller Interface. This options corresponds to #define USBH1_HC_IF.

#define USBH1_HC_IF                   1                   // 0 = custom, 1 = OHCI, 2 = NXP EHCI
