如何使能usb设备kernel中如何配置

Other Parts Discussed in Thread: AM3358

cpu使用的是am3358,现在想使能usb1的口用来连接一个4g模块,我配置了设备树,可是usb口总是无法发现设备

设备树配置如下:

&usb {
	status = "okay";
};

&usb_ctrl_mod {
	status = "okay";
};

&usb0_phy {
	status = "okay";
};

&usb1_phy {
	status = "okay";
};

&usb0 {
	status = "okay";
};

&usb1 {
	status = "okay";
	dr_mode = "host";
};

&cppi41dma  {
	status = "okay";
};

因为没有添加模块,都是直接编译到内核里,编译到内核中的驱动如下

root@cp6100:~# ls /sys/bus/usb/drivers
GobiNet       cdc_eem       cdc_ncm       hub           usb           usbfs
ax88179_178a  cdc_ether     dm9601        qcserial      usb-storage   usbserial

还需要什么配置吗,我尝试使用原装的内核配置文件tisdk_am335x-evm_defconfig也依然不可用

sdk版本是ti-processor-sdk-linux-rt-am335x-evm-02.00.02.11
