[Bug 1562431] Re: Huawei E3372 is not switched to modem mode automatically

Sun Mar 27 06:30:49 UTC 2016

Triaged given latest release tested, and appears a regression.

** Tags added: regression-release

** Changed in: systemd (Ubuntu)
       Status: Incomplete => Triaged

** Description changed:

  This "modem key" worked out of the box for me in ubuntu 15.10.

  However now, in 16.04, the "usb mode switch" is not done automatically
  (both is the modem is plugged at boot or after).

- I suppose it's an udev regression.
- 
- So, when the "key" is plugged (lsusb):
- 
- Bus 002 Device 010: ID 12d1:1f01 Huawei Technologies Co., Ltd.
- E353/E3131 (Mass storage mode)
- 
- $ usb_modeswitch -J -v 0x12d1 -p 0x1f01
- 
- => Bus 002 Device 011: ID 12d1:14dc Huawei Technologies Co., Ltd.
- 
- And now the device work as expected and can be choosed in network
- manager.
- 
- So there is no kernel problem for me.
