Incomplete rules for Samsung GT-B3730 LTE USB modem

[Marius B. Kotsbak]

Binary package hint: usb-modeswitch-data

The usb-modeswitch rules for Samsung GT-B3730 LTE USB modem needs to be expanded with the attached patch from Mandriva also found here:

http://svn.mandriva.com/cgi-bin/viewvc.cgi/packages/cooker/usb_modeswitch-data/current/SOURCES/usb-modeswitch-data-samsung-gtb3730.patch?view=markup&pathrev=606878

With that I can successfully send AT commands to the modem.

I'm wondering if using this as-is wouldn't actually cause a race-condition, if the device reacts to the message by appearing and disappearing; this would trigger Udev to re-run switching...

[Marius B. Kotsbak (mariusko)]

It works for me. The author of usb-modeswitch has also verified the rules and is going to include it into the next version.

[Marius B. Kotsbak (mariusko)]

Forget this. It will be done by the modem driver instead.

This is done by the driver I am developing here: https://github.com/mkotsbak/Samsung-GT-B3730-linux-driver
