usb_modeswitch detects Netgear AC327U USB stick as 2077:f000 , but does not switch to modem mode .

My laptop is running Ubuntu 14.04 9 Kylin .

Output of lsusb :

The message you are using is not a switch message, please try the msg from the file 2077:f000 in the usb_modeswitch data package.

Hi,

There is no file 2077:f000 in the default installation of modeswitch .

Came across 2077:f000 on net - but that was Terecom 3G , not Netgear AC327U .

Anyway switch message from even that ( Terecom 3G ) did not work , am still stuck .

Any other ideas ? Will be a big help ....

Thanks

We are usually referring to the latest release available here, not to the version of your distribution.

Brand names are not very telling when it comes to USB modems. USB IDs are much more relevant.

Can you post the log that is created when using the 2077:f000 configuration from the current data package?

There is no data file for 2077:f000 in the usb_modeswitch data package .

The data is updated for 14.04 .

Custom data file for 2077:f000 as found from net is given below ( its Digicom , not terecom as earlier mentioned - sorry . )

Code: Select all

raja@raja-Lenovo-G510:~$ cat /etc/usb_modeswitch.d/2077:f000

What you have or not have in your linux distro is something you should take up with the maintainer of that distro.
2077:f000 was included in the data package in May 2012, latest usb_modeswitch and data package are always available here http://www.draisberghof.de/usb_modeswitch/

I was referring to the current data package available here on this site.

It is now switching from 2077:f000 to 2077:a003 , after downloading and copying the 2077:f000 file from data package from this site .

Hit another bump now ; though it is switching to 2077:a003 ( modem mode ) , the device is not showing up on network manager .

Maybe the driver is not binding to the modem ...

Try to make the thing switch automatically (if it doesn't, check "/lib/udev/rules.d/40-usb_modeswitch.rules" and see if there is a line for your initial USB ID), then enable logging in "/etc/usb_modeswitch.conf".
