Problem with ZTE AC2787 in Dell Vostro 1400 Laptop
Posted: 24 Sep 2013, 19:37
I am using the same ZTE AC2787 dongle on identical Linux Mint 13 Maya systems (both running Linux 3.2.0-53-generic (x86_64) kernel) one on my desktop and the other on my old Dell Vostro 1400 laptop. I have installed usb-modeswitch on both (the latest package) followng the recommended process identically (as far as I can tell).
The same modem works just fine in my desktop, but it does not work in my laptop. In my laptop I suspect that it is not switching to the "modem" mode. The only difference that I can make out is in the lsub output after I plug in the device:
In desktop (where it is working) I get the following:
Bus 006 Device 005: ID 19d2:fff1 ZTE WCDMA Technologies MSM
In Laptop (where it is NOT working) I get:
Bus 005 Device 003: ID 19d2:fff5 ZTE WCDMA Technologies MSM
I will greatly appreciate if someone can help me solve the problem
Many thanks in advance.
PS: I have searched this forum and found posts wirh similar issue, but there I think the modem worked if it was plugged in during boot. I have tried that, but in my laptop it does not make a difference. It does not work. And the lsusb output remains the same.
