about adb permission

I met adb and fastboot permission deny by user priority when changing usb driver VID/PID.

I don't know the root cause, But you add one rule file to your udev/rules.d, it will ok.

reference:

e.g:

chechunli@chechunli-PC:rules.d $ cat 60-cell.rules 

SUBSYSTEM!="usb_device", ACTION!="add", GOTO="cell_rules_end"

# New Phone

SYSFS{idVendor}=="5678", SYSFS{idProduct}=="1234", OWNER="chechunli", MODE="0660"

LABEL="cell_rules_end"

the  idVendor and idProduct is get by using lsusb command.
