file:
If your 86Duino IDE is Coding 100/101/102/103:
# 86Duino
ATTRS{idVendor}=="0525", ATTRS{idProduct}=="a4a5", ENV{ID_MM_DEVICE_IGNORE}="1"
If your 86Duino IDE is Coding 104 and later:
# 86Duino
ATTRS{idVendor}=="0525", ATTRS{idProduct}=="a4a5", ENV{ID_MM_DEVICE_IGNORE}="1"
ATTRS{idVendor}=="0525", ATTRS{idProduct}=="8036", ENV{ID_MM_DEVICE_IGNORE}="1"
Save and close the file to complete and update Modem Manager setting.
