- DTS更改为如下配置：
这样配置， 切换为host枚举U盘正常。
root@firefly:/home/firefly# cat /sys/kernel/debug/usb/fc000000.usb/mode
device
root@firefly:/home/firefly# echo host > /sys/kernel/debug/usb/fc000000.usb/mode
root@firefly:/home/firefly# lsusb

但，切换为device模式后，还是无反应，表现为主机端未看到有任何枚举动作：
root@firefly:/home/firefly# echo device > /sys/kernel/debug/usb/fc000000.usb/mode
root@firefly:/home/firefly#
root@firefly:/home/firefly#
root@firefly:/home/firefly# cat /sys/devices/platform/fd5d0000.syscon/fd5d0000.syscon:usb2-phy@0/otg_mode
otg
root@firefly:/home/firefly# echo peripheral > /sys/devices/platform/fd5d0000.syscon/fd5d0000.syscon:usb2-phy@0/otg_mode
root@firefly:/home/firefly#
[u]root@firefly[/u]:/home/firefly#
- 完全使用客服发过来的devcie-only dtsi配置：
表现是默认为device模式，也是无反应，主机端未看到有任何枚举动作：
&usbdrd_dwc3_0 {
status = "okay";
dr_mode = "peripheral";
};
&u2phy0 {
status = "okay";
};
&u2phy0_otg {
status = “okay”;
};
&usbdp_phy0 {
/delete-property/ sbu1-dc-gpios;
/delete-property/ sbu2-dc-gpios;
/delete-property/ orientation-switch;
/delete-property/ svid;
/delete-property/ usbdp_phy0_orientation_switch;
/delete-property/ usbdp_phy0_dp_altmode_mux;
status = "okay";
};
&usbdp_phy0_dp {
status = "okay";
};
&usbdp_phy0_u3 {
status = "okay";
};
