Akhirnya saya menemukan solusinya...

Beberapa hari ini saya mengalami masalah dengan modem, saat saya mengecek dengan perintah dmesg | tail muncul seperti ini :

Pada bagian [ 127.539106] usb 2-1.1: device descriptor read/64, error -32 mengakibatkan modem tidak terbaca sebagai tty/dev/USB0 atau yang lainnya setelah menjalankan perintah load module a.k.a modprobe ke kernel sehingga wvdial tidak menemukan port yang akan digunakan untuk koneksi ke internet. Solusinya sebagai berikut :

1. Jalankan perintah lsmod

2. Jalankan perintah berikut
Spoiler! :

Code:
[email protected]:~$ sudo modprobe -r uhci_hcd

dan dilanjutkan dengan
Spoiler! :

Code:
[email protected]:~$ sudo modprobe uhci_hcd


3. Cek port usb modem yang aktif
Spoiler! :

Code:
[email protected]:~$ ls /dev/ttyUSB*

Hasilnya seperti ini :
Spoiler! :

Code:
/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2


4. Jika masih memiliki masalah sampai tahap 3 tambahkan script berikut ke /usr/share/hal/fdi/preprobe/10osvendor/20-broken-usb-sticks.fdi
Spoiler! :

Code:
<match key="@storage.originating_device:usb.vendor_id" int="0xkode_vendor">
<match key="@storage.originating_device:usb.product_id" int="0xkode_produk">
<merge key="info.ignore" type="bool">true</merge>
</match>
</match>

untuk melihat kode vendor dan produk gunakan perintah " lsusb "

Modem siap digunakan kembali.

Selamat mencoba
