take out USB device,system will output information like below.<br>
usb 2-1: USB disconnect, device number 12<br>
4） 拔下USB转接线，系统会输出类似如下信息：<br>
take out USB switch wiring,system will output information like below.<br>
ci_hdrc ci_hdrc.0: remove, state 4<br>
usb usb2: USB disconnect, device number 1<br>
ci_hdrc ci_hdrc.0: USB bus 2 deregistered<br>
<br>
USB HOST测试(USB HOST test)<br>
　　MY-IMX6-EK140 的USB HOST是插座形式，如要测试HOST功能，需要把自备USB头，并且将插座上的USB HOST信号线连接到USB头，此操作请找自己的硬件工程师请求支持。<br>
　　MY-IMX6-EK140 USB HOST is socket type，if need to test the function of HOST，need to connect signal line of USB HOST to the USB head self-prepared，?the operation need an assistance from hardware engineer.<br>
　　另外，请硬件工程师知晓，由于CPU的USB_VBUS供电能力不足，需要将“5V_core”与USB_VBUS相连。<br>
　　Moreover，please let engineer know that power supply capability of CPU的USB_VBUS is not enough，so need to connect“5V_core”with USB_VBUS<br>

测试说明(test instruction)<br>
MY-IMX6-EK140的TF卡接口不支持热插拔。<br>
MY-IMX6-EK140的TF card interface doesn't support hot plug<br>
<br>
测试方法(test method)<br>
1）为MY-IMX6-EK140断电。<br>
power off MY-IMX6-EK140<br>
2）将TF卡安装好板子的TF卡座上，并确认安装好。<br>
install TF card in TF card holder,and confirm the installation ok<br>
3）为MY-IMX6-EK140上电，待系统启动完成后进入系统。<br>
power on MY-IMX6-EK140,enter the system after booting is finished<br>
5）检查TF卡：<br>
check TF card<br>
＃ dmesg | grep "mmc0"<br>
TF卡正常则可以看到类似如下信息：<br>
if IF card is normal, then you can see information like below.<br>
mmc0: host does not support reading read-only switch. assuming write-enable.<br>
