Senjata baru untuk online kali ini adalah USB Modem EVDO Rev.A SmartFren AC682. Dengan kecapatan maksimum download up to 3,1 Mbps dan upload up to 1,8 Mbps. Bagaimana koneksi atau settingannya di Linux? Modem usb bermerk ZTE ini ternyata cukup mudah dikoneksikan dengan Operating System Linux. Beberapa tutorial membahas koneksi SmartFren AC682 dengan Linux Ubuntu, Linux Puppy, dan kali ini akan saya bahas dengan Linux Mint.
Saya (masih) menggunakan Linux Mint 9 Isadora dengan kernel 2.6.32-21-generic, berikut langkahnya:
- Koneksikan SmartFren AC682 pada port USB yang tersedia
- Buka aplikasi Terminal pada Linux Mint, login sebagai root
zaldi@zaldi-vanbook ~ $ sudo su
[sudo] password for zaldi:
zaldi-vanbook zaldi # - Periksa sambungan USB dengan perintah lsusb
zaldi-vanbook zaldi # lsusb

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub - Bus 002 Device 003: ID 19d2:ffde ONDA Communication S.p.A. menandakan SmartFren AC682 berfungsi sebagai storage atau media penyimpanan. Untuk beralih fungsi menjadi modem, klik kanan - Eject ikon SmartFren pada Nautilus (Explorer), atau dengan perintah eject /dev/sr0
zaldi-vanbook zaldi # eject /dev/sr0
- Periksa lagi sambungan USB dengan perintah lsusb, harusnya sudah berubah menjadi Bus 002 Device 003: ID 19d2:ffdd ONDA Communication S.p.A. seperti dibawah ini
zaldi-vanbook zaldi # lsusb

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub - Berikan modul baru pada kernel
zaldi-vanbook zaldi # modprobe usbserial vendor=0x19d2 product=0xffdd
- Periksa fungsi sambungan SmartFren AC682, dengan perintah dmesg|grep usb
zaldi-vanbook zaldi # dmesg|grep usb
