We are running Android 4.4.3 with kernel 3.10.53 in i.mx6dl platform. 

Recently we meet a problem that the usb port sometimes stops working when a udisk is plugged out after it is plugged in and being prepared by SCSI, by enabling some logs in scsi driver, I found that the problem usually happens when I plug out the device during a SCSI read(10) cmd is running, and the cmd will timeout, then the usb port stops working.

 

some logs are attached as files.

 

please help check if it is a bug of USB controller in i.MX6.
