Hi Ramy,
You can't just write arbitrary data to /dev/android_adb and expect it show up on the host side. adb (on the host) and adbd (on the device) communicate with each other via a structured protocol. The /dev/android_adb driver file is intended to be used only by the adbd daemon. You can't write to it yourself unless you send data using the adb protocol. -- Mike Lockwood Google android team --~--~---------~--~----~------------~-------~--~----~ unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel -~----------~----~----~----~------~----~------~--~---
