Description Sam H 2010-07-27 09:20:25 UTC
Description of problem:
Manual intervention is required to switch ZTE MF627/MF628/MF628+ HSDPA into "modem mode".

Version-Release number of selected component (if applicable):

How reproducible:
Every time.

Steps to Reproduce:
1. Plug device in.
Actual results:
Unable to use device as a mobile broadband modem. Oddly it does not show up when disks are listed with fdisk -l or when blkid is run.

Expected results:
Should be switched into "modem mode" without any user intervention.

Additional info:
"Original" device information:
Bus 001 Device 014: ID 19d2:2000 ONDA Communication S.p.A. ZTE MF627/MF628/MF628+ HSDPA

Have to switch product ID to 0031 and send the message "55534243123456782000000080000c85010101180101010101000000000000" to the endpoint 0x01 eg. "usb_modeswitch -v 19d2 -p2000 -V 19d2 -P 0031 -m 0x01 -M 55534243123456782000000080000c85010101180101010101000000000000".

Have to then manually unload the usb-storage module. "rmmod usb-storage". This means that all usb storage devices have to be unplugged. 

The first time this device is plugged in after a reboot I am able to mount it and access the MS Windows driver files and if I then eject the device it can be used via network-manager.

I was wrong about having to unload the usb-storage module. Didn't think something like that would be required.

Comment 2 Sam H 2010-08-13 21:47:03 UTC
If the MessageContent in '/etc/usb_modeswitch.d/19d2:2000' is changed to '55534243123456782000000080000c85010101180101010101000000000000' this device works however I'm not sure if this will prevent other ZTE devices from working.

A fix for this will be available in the next data package release. Source: http://www.draisberghof.de/usb_modeswitch/bb/viewtopic.php?p=3113#3113
