The partitions an apk can write to are mounted with the setuid bit disabled. These are things you need to incorporate in a custom build of android - the proper way is likely to have device file created with an appropriate unix-level group to control access - possibly a custom one.
A "generic android device" doesn't have a tty suitable for connecting to an external device anyway. Sometimes there's a debug serial port in the hardware, but you would need platform customizations or a non-secured (or broken-into) build in order to access it. -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel
