Failure with Huawei K3520

[miguelquiros]

I have tried linux_huawei_unlocker with Huawei K3520 modem and had no success.
The program test the ports /dev/ttyUSB2 /dev/ttyUSB1 and /dev/ttyUSB0 (these are automatically created when plugin the modem) and says that the three of them are inactive and then the program exits.
After this, I have successfully unlocked the modem with MobilePartner, connected to the network through the modem and I am actually sending this message through it. (Hence I cannot make further tests, sorry).
According to the HELPME file included in the software, I add the requested information:
- Your Linux distribution and version (e.g. Ubuntu 12.04)
Ubuntu Trusty
- Your version of Python and pySerial (if known)
python 2.7.5-5ubuntu3
python-serial 2.6-1build1
- The model of your modem
Huawei K3520
- The country of purchase of your modem
Spain
- The original carrier for your modem
Vodafone
- The carrier of the SIM you used in the unlock process
Simyo
- Any problems, failures or error messages
Ports /dev/ttyUSB2, ..1 and ...0 regarded as "inactive". The program then exits.
- Any suggestions for improvement.
I do not know, more verbose error messages???
I am affraid I cannot be of more help. Thanks anyway for making this software for the world.
