Storage [Solved] Usb power consumption error on usb otg (root required)

So I was having this power consumption error with my hp pendrives and ssd. Searched the net for a software solution but couldn't find any except the terminal emulator command method which didn't work for me. So I tried to improvise on the idea and finally succeeded. It's basically the same idea but in a different way.

Clarification- this method is to only override the power consumption error which prevents the mounting of the removable device. So the power consumption will be still there and the charge will be drained at a fast pace if used for long time. U can use the method for copy files between your phone and the pendrive or for viewing for a small time. Adequate charge is therefore highly recommended.

Method-
1.plug in the device into the otg cable and then the cable into the phone.
2.wait till the power consumption error message is displayed.
3.using a root explorer(e.g. es file explorer) go to the folder 'root>sys>bus>usb>devices>1-1'
4.open the file 'bConfigurationValue' with a text editor(es text editor in my case). It should be blank. Edit and put the value 1 and save the file.
5.Your device will now be mounted and the message will be displayed in the statusbar.
6.Your device is now explorable.

N.B.- In some cases instead of the power consumption error message, usb devices disabled message is shown. If it happens try unplugging and replugging till the power consumption error message is shown.

Disclaimer -
1.This method worked for me and so I shared. I wont be responsible for any damaged os or device.
2.I dont knw if anyone has shared the method before. Didnt find anywhere when I searched.

Device used- Xperia U on rooted ics. Should work for other related devices too.

Video tutorial - Search YouTube for 'How to solve Usb power consumption error on
usb otg (root required) [HD]'
(I will add the link once I m allowed to)
Thanks to SohaibAhmed for the video tutorial.

Credits- I got the idea from the terminal emulator command method. And I dont know who originally shared it. So thanks to him.

This is my first submission to xda. Plz be considerate about any mistakes. Thank you all.

if this error is there everytime u plug in the device then it is because of a bad cable or usb storage. I use to get this when I plug in a sd card reader with a bad card or a pendrive formatted as ntfs. plz check whether the pendrive u plugged is mounted in a pc. or try after a reboot of the phone.
