Just an addition: in our git repository, Benjamin manages a branch for Android where hid-multitouch.c is patched to reflect the above information. The problem we have is that kernel management for Android appears to be decentralized (each vendor is supposed to provide their own patched kernel) and we have nobody to submit this version to. Hopefully, our contact at Google will find the time to use protocol B in the next version of Android and we'll be able to forget all this.
