Package: usb-modeswitch
Version: 2.5.0+repack0-1
Severity: normal
Dear Maintainer,
I have a Telewell TW-3G HSPA+ modem (usb). When it is plugged the device
is identified as usb mass storage. See the kernel log below (journalctl
-fk):
2017-06-11T12:29:52+0000 mithlond kernel: usb 1-7: new high-speed USB device

Then usb-modeswitch (I presume) disconnects the device (idProduct=98ff)
and immediately connects it again as another device (idProduct=9801)
which is supposed to be the actual 3G modem. See the kernel log below:

But there is the problem: this new device is still a usb-storage ("USB
Mass Storage device detected"). Network Manager can't see the 3G modem.
This all worked fine with Debian 8 (Jessie) but broke in Debian 9
(Stretch).
Extra info: If I run manually
modprobe usbserial vendor=0x1c9e product=0x9801
the 3G modem starts working.
