Arch Linux

Description:
For a few months, connecting my android smartphone to my computer has resulted in the following error messages:

The phone is not detected further and I cannot access content of the SD card.

I found the following bug report which seem to be related:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1047527

According to this bug report, the CONFIG_USB_OTG option seem to be responsible.
This option was not enabled on archlinux until kernel 3.14, as attested by this commit: https://projects.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/linux&id=be17a7f9fa44af6d1c48c08196f003fb365da822

Could the CONFIG_USB_OTG option be turned off again ?


Additional info:
* affected packages: linux 3.14.x


Steps to reproduce:
Connect my android phone to my computer
