# mtk_root - USB access for Android debugging and MediaTek BROM recovery.
#
# Installed by mtk_root/install.sh. Scoped to two vendor IDs on purpose.
#
# MODE="0660" plus GROUP + TAG+="uaccess", NOT MODE="0666":
#   - 0666 grants every process on the machine read/write access to the device
#   - uaccess grants access to the user logged in at the physical seat, which
#     is what is actually wanted, and it is revoked on logout
# A rule matching idVendor=="*" with 0666 applies to every USB device attached
# to the system - storage, security keys, everything - not just phones.

# Google (Pixel): adb + fastboot
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", MODE="0660", GROUP="adbusers", TAG+="uaccess"

# MediaTek: BROM / preloader / DA modes, used by mtkclient.
# 0e8d covers the BROM (2000), preloader (2001) and DA download ports.
SUBSYSTEM=="usb", ATTR{idVendor}=="0e8d", MODE="0660", GROUP="adbusers", TAG+="uaccess"

# MediaTek devices also expose a CDC-ACM serial port in preloader mode;
# mtkclient opens it directly.

# Ulefone's own USB vendor ID, if it differs from MediaTek's, is UNKNOWN until
# the device is attached: run `lsusb` with it plugged in and add a line here.
