关于AM335X USB0使用host模式

您好，AM335X usb0设置host模式，软件部分是不是只是在这个地方修改就行了，我的内核版本3.2

static struct omap_musb_board_data musb_board_data = {
.interface_type = MUSB_INTERFACE_ULPI,
/*
* mode[0:3] = USB0PORT's mode
* mode[4:7] = USB1PORT's mode
* AM335X beta EVM has USB0 in OTG mode and USB1 in host mode.
*/
.mode = (MUSB_HOST << 4) | MUSB_HOST,
.power = 500,
.instances = 1,
};

请问一下3.2的内核中能否集成USB网络驱动 CDC MBIM接口功能

您好，请问下我的USB1也是用HOST模式，内核启动打印有关USB的信息如下

插U盘启动内核，打印信息中没有识别U盘

我的vbus上拉到5v，id脚接地，请问还有别的问题导致U盘上电不识别吗

我查查硬件吧，USB1host模式识别U盘了，USB0再看看
