RB922UAGS-5HPacD with LTE Module Huawei ME909u-521

Hello Guys,

I need help to make LTE module of Huawei ME909u-521 work on RB922.
Before I had Board RB912UAG-5HPnD as make it work fine just as I changed form Routerboard the USB to become PCI.
Right now on new board there is no USB button under Routerboard.
The LTE card is recognized by board but under USB. Via Terminal I tried to execute “/system routerboard usb> set type=mini-PCIe usb-mode=automatic” but nothing happen.
Now the current version is 6.30.1.

Do you have any idea how that problem can be fixed?

Thank you

LTE interfere should appear.
then you add dhcp client to lte interface and set apn/pin

you could enable

/system logging
add action=memory topics=async,debug 
add action=memory topics=lte,debug

is it is still not working
try to use /sy rou usb power-reset
