usbmode sits in loop after install

Hello all,

i'm trying to get a Huawei ME909s-120 LTE Card (12d1:15c1) working on a PC Engines APU2 (amd64) in MBIM Mode.

Right after installing "usb-modeswitch" on OpenWrt Snapshot r6397-7cc9914 prints constanstly:

[   59.838090] usb 1-1.3: usbfs: process 6946 (usbmode) did not claim interface 1 before use
[   60.048534] usb 1-1.3: usbfs: interface 1 claimed by usbfs while 'usbmode' sets config #0
[   60.131996] usb 1-1.3: usbfs: process 7032 (usbmode) did not claim interface 1 before use
[   60.342459] usb 1-1.3: usbfs: interface 1 claimed by usbfs while 'usbmode' sets config #0

These Messages are also printed on LEDE 17.01.4 r3560-79f57e422d, but only once.

This HW config is working fine with cdc_mbim on Debian with a 4.9 Kernel and their usb-modeswitch implementation.

Any hints?

Thanks.

Sydney

Option 1
Uninstall usb-modeswitch

Option 2 (if you need usb-modeswitch)
Edit /etc/usb-mode.json file, change it to show
