I've seen somewhere stated that this behaviour is because both android and linux run on same kernel, and same situation goes to developing android on mac. Both OS runs in very similar OS kernel with Android, that is why they don't need any drivers. These are just something I remembered seeing from other threads, can't give 100% sure
UPDATE #1: The Android site also mentions this:
If you are developing on Windows and would like to connect an Android-powered device to test your applications, then you need to install the appropriate USB driver. ...
If you're developing on Mac OS X or Linux, then you probably don't need to install a USB driver. To start developing with your device, read Using Hardware Devices.
UPDATE #2: There's a comment on StackOverflow regarding libusb
. I think this may be the reason why Linux does not need additional drivers.
Actually adb under Linux accesses USB devices using libusb without any specific kernel driver. Also adb has a list of vendor IDs which it is allowed to use, but this does not explain the problem in question, because vendor IDs for both phones are the same. And in case of permission problems due to missing udev rules adb devices clearly shows “no permissions” in the list, so this is also not the cause of this problem.
