When I connect my device to my Linux laptop (debian-Ubuntu) I don't get any output in
adb logcat
If I connect it to another laptop it works fine
in KDE I can open the Directory and copy files, so USB is working
it seems like
adb devices
finds the device:
List of devices attached
042some_numbers00 device
but it stays disconnected somehow
I created a file
sudo nano /etc/udev/rules.d/99-android-mtpfs.rules
and added
# Nexus 5 (alias Nexus 4) "sudo lsusb" shows: 18d1:4ee2
SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4ee2", MODE="0666" GROUP="androiddev", SYMLINK+="android%n"
and I added:
echo 0x18d1 >> ~/.android/adb_usb.ini
then I rebooted Ubuntu and it worked!!!
