Have you tried taping the USB 3.0 pins?

I have did everything it say
disable the usb3 pins , and try to run the scripts
but still it get disconnected after 4-5 seconds

Perhaps try keep it simple, lets get rid of the scripts for now.
Just try the following.

system resource usb print

Should spit out something like this.

DEVICE VENDOR NAME SPEED

0 2:1 Linux 3.3.5 ehci_hcd RB400 EHCI 480 Mbps
1 1:1 Linux 3.3.5 ehci_hcd RB400 EHCI 480 Mbps
2 1:2 Sierra Wireless, Incorporated Sierra Wireless MC7430 Qualcomm\C2\AE Snap... 480 Mbps

Depending on how many buses etc your routerboard has you need to issue the following command but need to change the bus number to suit your situation.
I've underlined what I think is the bus number on my routerboard.

system routerboard usb power-reset bus=1 duration=5

If that doesn't work try longer or shorter usb bus resets.
Also try the modem in a laptop if you have one available. Mine worked excellent in a laptop with kali linux for an OS.

now it’s working ..
It hasn’t disconnected for 15 min now

so I will put this script at startup and give it a try for a few days

Thanks !
