TL-MR3420-V5 gpio usbpower control

Hi!
I'm testing two models of routers that make part of the same "group" and "specs".

One is the TL-MR3020-V3 and it has the gpio usbpower control:

root@TL-MR3020-V3:~# ls -l /sys/class/gpio/usbpower/value 
-rw-r--r--    1 root     root          4096 Jul 19 00:41 /sys/class/gpio/usbpower/value
root@TL-MR3020-V3:~# cat /etc/os-release

machine                 : TP-Link TL-MR3020 v3
root@TL-MR3020-V3:~#

And another is the TL-MR3420-V5 whitch unfortunately doesn't have the gpio to control usbpower

Somebody have the same needs? Please help to get usb power control.

Thank you in advance.
