Since the other threads regarding that modem did not reflect my problem I start a new here:
I am trying to get my E3372 working, however I do not succeed switching to modem mode.
When plugged in the cyan light is on, and network manager shows that the modem would be connected, though I cannot send/recieve data.
Software installed is:
usb-modeswitch: 2.2.5+repack0-1
usb-modeswitch-data: 20150627-1
Kernel 3.16 ( Debian 8 )
I can find the modem in the ConfigPack:
tar zxOvf /usr/share/usb_modeswitch/configPack.tar.gz 12d1:157dSince it does not switch automatically, I tried to do it manually, first:
sudo usb_modeswitch -H -v 0x12d1 -p 0x157d
I get:

Huawei E3372 Change Imei Number

but it doesn't change, lsusb still shows me 12d1:157d
and when I try:

Huawei E3372 510

sudo usb_modeswitch -J -v 0x12d1 -p 0x157d

Huawei E3372h-153 Change Imei

I get:

Unfortunately I don't understand that error message;
Anyone an idea how to get the modem working?
Thanks!
