I purchased a Huawei e5331 device, I can use it via wifi, but not via usb. First of all sometimes the system cannot manage to recognize as usb modem, sometimes yes (usb_modeswitch installed). If I reboot the device while connected it's recognized.
When I can get it recognized this is the lsusb output:
this is dmesg output:
Bus 001 Device 005: ID 12d1:1506 Huawei Technologies Co., Ltd. E398 LTE/UMTS/GSM Modem/Networkcard
and I can see ttyUSB0 and ttyUSB1 under /dev. Network manager recognizes there is a mobile broadband option, correctly reading my provider name, but after having it configured it cannot connect.

So, I tried with wvdial, this is the result:
I tried both with ttyUSB0 and ttyUSB1. I tried on Ubuntu 12.10 x86_64 and Linuxmint 14 with the same result.
--> WvDial: Internet dialer version 1.61
--> Initializing modem.
--> Sending: ATZ
--> Sending: ATQ0
--> Re-Sending: ATZ
--> Modem not responding.
It's a really strange problem, it seems that the modem is recognized but doesn't work. I didn't find nothing on the internet about Huawei e5331 and linux.
Thank you in advance.
Ok, I solved with this:
after you install, it doesn't do a normal modem connection, but some sort of tethering with the device that adds a wired network connection.
Hope this helps someone with the same problem. Thank you anyway!
