USB ADB doesn't work on snowball because because of the limited functionality the board currently support.

[Anmar Oueja (anmar)]

I thought it was intermittent but when I saw it reported at 100% failure rate, I thought things gotten worse.

[Thomas Espersson (espersson)]

I also believe this is an old 'known' issue, what Patrik did was correct, to report it and make it visible even though it is a already existing issue

[Kalle Vahlman (kvahlman)]

Just to note that Mathieu's comment on "limited functionality the board currently supports" is not the usual USB issue:

ADB over USB is working fine on Gingerbread images from Igloo Community, so this will most likely be a bug in the newer kernel.

[Anmar Oueja (anmar)]

This is an important bug to fix since without USB ADB, it will make Android developement very difficult.

Thomas: Can we deligate this to somebody in the ST-E snowball team to look into it?

[Anmar Oueja (anmar)]

Need to be verified against the 3.1 kernel once it is ready.

[Mathieu Poirier (mathieu.poirier-deactivatedaccount)]

The Android landing-snowball build has been using kernel 3.1 for a couple of weeks now. Abhishek can test at any time but I doubt it will work as no user space tailoring have been made.

Also observed on https://android-build.linaro.org/builds/~linaro-android/landing-snowball-12.01-release/#build=5

[Anmar Oueja (anmar)]

This is now on our radar and will get addressed for the 2012.02 cycle.

[Lee Jones (lag)]

This issue is now fixed and should be fully working in 12.12.

Issue was due to missing kernel CONFIGS:

CONFIG_USB_GADGET_MUSB_HDRC=y
CONFIG_USB_MUSB_HDRC_HCD=y
CONFIG_USB_MUSB_OTG=y
CONFIG_USB_G_ANDROID=y
CONFIG_SWITCH=y

Fix confirmed in https://android-build.linaro.org/builds/~linaro-android/snowball-ics-gcc46-igloo-stable-blob-12.02-release/#build=1
