cdc_mbim error kernel 4.9

Hi, in kernel 4.8 I was able to connect to my usb modem using :

echo "AT+CFUN=1" > /dev/ttyUSB0
mbimcli -d /dev/cdc-wdm0 --register-automatic
mbim-network /dev/cdc-wdm0 start

And then proceeded to assign ip properties to the wwan interface.

But after upgrade to 4.9 the mbim-network script hangs and kernel just shows this errors :

arch kernel: cdc_mbim 3-1:1.0: Error in flush path: -32 
arch kernel: cdc_mbim 3-1:1.0: Unexpected error -75
arch kernel: cdc_mbim 3-1:1.0: Error in flush path: -32
...

Any ideas how to solve this ? .

Thanks.
