I am new here and have found some answers but no solution for this problem, so I try again by a new thread (sorry if I missed an answer)

I want to charge my tab through the usb connection to my pc or in my car and not only through the AC-adapter.

In the development discussion is this theme going on (page 101):

I don't kmow why this error, I am root, but anyway, I changed this value directly using root explorer and a text editor and it works for me, now I have enabled usb and non-samsung-charger charging.

Thanks a lot!

You are using Terminal Emulator ? If yes then no need to write adb shell, just su first then echo 1 > /sys/class/power_supply/battery/force_usb_charging
I followed this instruction by Using the Terminal Emulator. Changing to "1" works fine until I restart my tab, than its back to "0" and I do have to change it again.

How can I keep the wanted setting to "1" ?

Thanks for help in advance
