IMX6UL USB host problem

[linhaiboyy]

hi，

　　　I　am use  platform is imx6ul,  linux kernel 3.14.38 . I am use the imx6ul as the usb host device ,  when  the usb in communication , I am pull out the usb port,  the device prompt the error : 

   usb 1-1.2: device no response, device descriptor read/64, error -11   .  How can I solve  this  problem ？？？

Hi

for dts options one can look in sect.41.2.6 Changing the Controller Operation Mode

attached Linux Manual. Also one can test with Demo Images

Latest L4.9.11 release :

Hi,

Which USB Device are you trying to connect to the processor ?

[linhaiboyy]

I use imx6ul as usb device and  other one  imx6ul device as  host  .  Devices use kernel code , it is printer driver code ，modify  PID and UID,  it can  communicate to each other.  Non communication, usb host and usb device plugged normal.  Communication ,  usb host and usb device plugged abnormal， and  the usb host prompt the error ：   usb 1-1.2: device no response, device descriptor read/64, error -11   

[rajathks]

Can you send me the DTS file where you changed the USB configuration to HOST ?

On the same setup if you connect any other usb device ,is it detecting ?? can you try connecting USB having Hi & full speed and attach the log file ?

You didn't get what i asked i guess. I don't want .ko files snapshots. Please let me know on the same setup if you connect some other USB device is it detecting on the imx6ul processor in HOST mode?. Check lsusb and confirm whether usb detects with some other USB device 

[linhaiboyy]

The usb device can be detected on the  imx6ul processor in HOST mode . I am use  lsusb can find my usb device , and can find some other USB device
