Configure udev Rules

Automatic setup (recommended)

Run the single command below. It writes both the EDL-mode and ADB-mode rules in one shot:

printf 'SUBSYSTEMS=="usb", ATTRS{idVendor}=="05c6", ATTRS{idProduct}=="9008", MODE="0666", GROUP="plugdev"\nSUBSYSTEMS=="usb", ATTRS{idVendor}=="05c6", ATTRS{idProduct}=="9135", MODE="0666", GROUP="plugdev"\n' \
  | sudo tee /etc/udev/rules.d/51-qcom-usb.rules

Then restart udev:

sudo systemctl restart udev

If your device is already connected, unplug and replug the USB cable.

Manual setup

Step-by-step — create the rules file manually

Navigate to the udev rules directory:

cd /etc/udev/rules.d/

Check whether the file already exists:

ls -l 51-qcom-usb.rules

Create or open the file:

sudo vi 51-qcom-usb.rules

Add (or verify) the following content:

# Qualcomm EDL mode
SUBSYSTEMS=="usb", ATTRS{idVendor}=="05c6", ATTRS{idProduct}=="9008", MODE="0666", GROUP="plugdev"

# Qualcomm ADB mode
SUBSYSTEMS=="usb", ATTRS{idVendor}=="05c6", ATTRS{idProduct}=="9135", MODE="0666", GROUP="plugdev"

Restart udev:

sudo systemctl restart udev

Confirm plugdev membership

If your user account is not in the plugdev group, device access will fail even with correct udev rules.

Check your groups:

groups $USER

If plugdev is missing, add yourself:

sudo usermod -aG plugdev $USER

Log out and back in (or reboot) for the change to take effect.
