[KERNEL][ICS][anykernel] USB Host mode (OTG) driver for Nexus S [BUILD 5]
This kernel will enable some very early, and rough usb OTG support for your phone. Currently the phone DOES NOT
give out power, so you NEED
an external power source to be able to use this kernel. This is true for ALL
USB devices, even with those that have their own power source, and doesn't requre external bus powering. Solving this limitation is a TODO, but we cannot guarantee anything. There are some other phones that have usb host support the same way this kernel has (eg. they need external power), like the Nexus One
, and there is also a community using this, so if you're saying that usb host support has no sense if you need an external power source then you are definitely mistaken.
This kernel is built upon the official ICS kernel from google's git repository. It is possible to port this to older ROMs (like CM7, or stock Gingerbread). Ask your favourite kernel developer to do this for you.
Credits goes to:
- The misterious guy at Samsung(?) called chul2 for the original s3c host drivers
- Kevin Hester (kevinh, probably also nicknamed geeksville, punkgeek and humcycles) for fixing the s3c host driver for the Samsung Galaxy Tab
- Ever kernel developer at teamhacksung for bringing ICS goodness to Galaxy S
This is a very early, and very rough usb host support. Expect crashes, freezes and things that are not working! You will also need external power (probably through a Y-cable or a powered usb hub, see the device connection guide below). Also make sure you are only using USB 2.0 (high-speed) devices. The driver does has some quirks with USB 1.x low-speed and full-speed devices, like mice, keyboards and similar things. Read the FAQ for more information about them. And of course it doesn't work with USB 3.0 (super-speed) devices.
