[Bug 1173566] Re: 19d2:2000 ZTE HSDPA Modem MF627 MF628 not recognized by network-manager in Ubuntu 13.04

 

Thank you for you prompt reply. Sorry about the delay in my comment. I
was actually expecting some email notification from activity on the
thread.

Unfortunately, I don't have access to the hardware. Its at remote
location (thus the 3G modem) and I was there just delivering new PC with
updated OS and some support to get things going. They resort now on the
old PC with Ubuntu 11.04 where this modem is working. I can't remember
if it worked out of the box with that one or if it required some
fiddling. So I can't do any testing with it any time soon...

Title:
  19d2:2000 ZTE HSDPA Modem MF627 MF628 not recognized by network-
  manager in Ubuntu 13.04

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Hello,

  I just had to notice that my ZTE HDPA USB Modem is no longer working in Ubuntu 13.04 - but in 12.04 it worked.
  lsusb lists the device  as
  "ID 19d2:2000  ZTE WCMA Technologies MSM MF627/MF628 HSDPA/HSUPA"
  but the internal flash memory as well as the modem itself are not recognized by nautilus or the network-manager respectively.
  Older workaround I found anywhere here with killing modem-manager does not work.

  Ubuntu release 13.04 3.8.0-19
  usb-modeswitch 1.2.3+repack0-1ubuntu3
  modemmanager 0.6.0.0.really-0ubuntu5

  WORKAROUND: 1. I added the modules (not sure if this is really necessary)
  usbserial
  option
  in /etc/modules
  2.picked up the matching config file (e.g. "19d2:2000" - this is the device ID) from /usr/share/usb_modeswitch/configPack.tar.gz and added the line "ReleaseDelay=3000". Then saved the file at /etc/usb_modeswitch.d
  3. finally I created a file named "usb-storage.conf" in /etc/modprobe.d" and copied in these lines:
  # Increase the default delay to avoid conflict with usb_modeswitch

  options usb-storage delay_use=3

  4. Connected the usb-modem, waited about 10-15 seconds until the
  internal SD-card was mounted and the the modem recognized by the
  modem-manager.
