Can't get the Android open accessory kit to work with Samsung galaxy S I9000 / Cyanogenmod 7.1

I have a Galaxy S I9000 with Cyanogenmod 7.1. (Android 2.3.7) When I try to install Demokit on the device I get :

[2011-10-14 13:01:43 - DemoKit] Installation error: INSTALL_FAILED_MISSING_SHARED_LIBRARY

from logcat:

10-14 13:13:30.675: ERROR/PackageManager(205): Package com.google.android.DemoKit requires unavailable shared library com.android.future.usb.accessory; failing!

However, it does work on a Nexus S with the same distribution. Any ideas?

Thanks,

UPDATE

Managed to install. see link: http://www.google.com/url?sa=D&q=http://forum.cyanogenmod.com/topic/14454-cm7-discussion-of-nightlies/page_st_260&usg=AFQjCNGMBI-09rbdzYZq7AwY-_BZpsiONw

However, still can't get the DemoKit app to communicate with the arduino board. I get the following in logcat when connecting the USB :

10-14 21:15:45.313: ERROR/Setting(1451): Intent Action android.intent.action.ACTION_POWER_CONNECTED 10-14 21:15:45.313: ERROR/Setting(1451): Battery charging. plugType =2 10-14 21:15:45.315: ERROR/Setting(1451): Charging is of type USB= 2 10-14 21:15:45.315: ERROR/Settings(1451): [MTP] assume media player mode, USB is connected. 10-14 21:15:45.567: ERROR/OggEx开发者_JAVA百科tractor(255): readNextPacket err -1004

I just wrote an answer to a similar question that might be of help to you

When I was digging around in the CyanogenMod 7.1 kernel sources for my Galaxy S2 I found that the USB accessory driver missing from kernel 2.6.35.7 (I think the kernel .config flag for this driver is CONFIG_USB_ANDROID_ACCESSORY).

I have tried several ways to get the ADK to work but the only "solution" to this problem that I've managed to get working was to switch to an experimental release of CyanogenMod 9 (ICS 4.0.3)

Hope this helps
