Using udev to connect to Android device

I am using method from this page to connect my android mobile to my Debian9 system using udev rules: https://android.stackexchange.com/qu...10/39437#39437

* Find vendor and product ID using lsusb or dmesg output:
* As root, create rules file: /etc/udev/rules.d/51-android.rules
* Insert:

Code:

SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e22", MODE="0666" GROUP="androiddev", SYMLINK+="android%n"

* Restart udev:

Code:

systemctl restart udev

However, the device is not getting recognized on disconnecting and reconnecting, even after rebooting. Where is the problem and how can it be solved? Thanks.

I do know that a udev rule matches need to use matching of the attributes of the device and the attributes from one single parent device.

References:
https://wiki.archlinux.org/index.php/udev
http://www.reactivated.net/writing_u...les.html#basic

So I'm wondering if the rule matching shouldn't use 'SUBSYSTEM="usb"' instead...

Code:

SUBSYSTEM=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e22", MODE="0666", GROUP="androiddev", SYMLINK+="android%n"

Anyway, you can investigate valid attributes for a given device using the following:

Code:

lsusb

The bus and device node for a given device then can be used to get the device attributes, eg for bus 003, device 004

Code:

udevadm info -a -p $(udevadm info -q path -n /dev/bus/usb/003/004)

Hope this helps.

PS: I note your original rule was missing a comma between MODE and GROUP assignment parameters.

Hi

as a local user run

Code:

groups

does this group exist?

I think plugdev group might be better?

personally I prefer android-file-transfer

I think following line is working:

Code:

SUBSYSTEM=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e22", MODE="0666", GROUP="plugdev", SYMLINK+="android%n"

Now when I turn on MTP connect on android device, it appears in the file manager on desktop and I can access the files on the device. Thanks.

I use WiFi File Transfer Pro:

https://play.google.com/store/apps/d...iletransferpro

Very easy to use and has always worked for me. It basically acts like a server on your mobile device. Tip: Do not logout from your browser. Just clear your history and shut down the browser.
