What steps will reproduce the problem?
1.Connect the USB cable to the USB OTG.
2.Reboot the device through adb reboot or through normal serial cable by the 
command "reboot".
3.

What is the expected output? What do you see instead?

adb cable should be detected even though device is rebooted multiple times. 

What version of the product are you using? On what operating system?

VARSCITE DM3730 SOM, Gingerbread 2.3.4(OS), 2.6.37 Kernel version.

Please provide any additional information below.

Whenever user gives adb reboot or reboot, kernel reboot the system with the 
warm reset. Some times after reboot adb cable is not detected. After looking 
into the errata of the TI DM3730, i came to know that, some modules(USB OTG) 
will not reset with the warm reset, workarounds didn't work. So i tried the 
cold reset instead of the warm reset. With the cold reset possibility of the 
getting the issue is reduced, but not completely eliminated.
