Loading Kernel Modules in latest firmware

[Speedy1205]

Hi Guys,

I still try to figure out the issue with the LTE Modems and have a question to it.

This is how the kernel worked in version 374.42_2

Jan  1 01:00:15 kernel: scsi 0:0:0:0: CD-ROM            HUAWEI   Mass Storage     2.31 PQ: 0 ANSI: 2
Jan  1 01:00:15 kernel: scsi 0:0:0:0: Attached scsi generic sg0 type 5
Jan  1 01:00:15 kernel: scsi 1:0:0:0: Direct-Access     HUAWEI   TF CARD Storage  2.31 PQ: 0 ANSI: 2
Jan  1 01:00:15 stop_nat_rules: apply the redirect_rules!
Jan  1 01:00:15 kernel: sd 1:0:0:0: Attached scsi generic sg1 type 0
Jan  1 01:00:15 kernel: sd 1:0:0:0: [sda] Attached SCSI removable disk
Jan  1 01:00:15 kernel: usb 2-2: USB disconnect, address 2
Jan  1 01:00:15 rc_service: hotplug 570:notify_rc restart_nasapps

and later

Jan  1 01:00:15 kernel: usb 2-2: new high speed USB device using ehci_hcd and address 3
Jan  1 01:00:16 RT-AC56U: start httpd
Jan  1 01:00:16 kernel: usb 2-2: MAC-Address: 0c:5b:8f:27:9a:64

Jan  1 01:00:16 kernel: scsi2 : usb-storage 2-2:1.3
Jan  1 01:00:16 hotplug: add net usb0.
Jan  1 01:00:16 hotplug: set net usb0.
Jan  1 01:00:16 kernel: scsi3 : usb-storage 2-2:1.4
Jan  1 01:00:16 crond[619]: crond: crond (busybox 1.20.2) started, log level 8

The newer kernel just loading all modules ????:

So the cdc_ncm is the fast driver which LTE user wants to use, even with workaround. In the new version its just loading all modules and uses the Option driver and ppp to connect the Modem to the ISP.

Is there a way I can force a device o use a specific kernel module ? I`m not so familiar with this OS, in my SUSE box I created some custom udev rules and that worked. How I can do this with this box RT-AC56U ?

Any suggestion are welcome.

PS> that's why in the new version the workaround with the services-start script doesn't work anymore because its loading the wrong modules.
