As January -2013, some newer kernels are demonstrating bugs when toggling the sdmux on/off -from the host using the sdmux.sh script. Here's a list of what's currently -known: - - * 3.2.0-31 - Works - * 3.2.0-32 - Looks like it will work. Target boots, so its reading partition 1. - However, it can't mount the root partition. This likely implies that the host - is still supplying some amount of current to the USB port. - * 3.2.0-34 - Not working at all. sdmux.sh can turn off the port, but not turn - it back on. +About ADB +--------- + +An issue has been discovered but not yet resolved upstream with ADB. The +way the ADB daemon runs on the host prevents the sdmux.sh script from +properly managing the device. Details and the proposed fix can be found +here: https://android-review.googlesource.com/#/c/50011/
