WVDIAL dan Modem Venus VT-18 di Slackware

Pertama kali tancap modem di port usb dan hidupkan komputer :)
check list device yang tertancap di port usb.

# lsusb

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 003 Device 002: ID 03eb:0902 Atmel Corp. 4-Port Hub

Bus 003 Device 005: ID 1d09:aef4 TechFaith Wireless Technology Limited

Disini terlihat dibaris ke 5 vendor id 1d09 dan product id  aef4 itu yang akan kita gunakan nanti.
oke dilanjut dengan perintah

#dmesg

saya edit hasilnya karena terlalu panjang dan supaya lebih mudah di pahami.

usb 3-2.3: reset full speed USB device using ohci_hcd and address 3

sr1: CDROM (ioctl) error, command: cdb[0]=0x46 46 00 00 00 00 00 00 00 2000

sr: Sense Key : 0x4 [current]

sr: ASC=0x0 ASCQ=0x0

Terlihat kernel mencoba mengaktifkan device CDROM di /dev/sr1 tetapi gagal
(catatan:node /dev/sr0 sudah teralokasikan untuk DVD-RW).

usb 3-2.3: reset full speed USB device using ohci_hcd and address 4

scsi 5:0:0:0: Direct-Access     Qualcomm MMC Storage      2.31 PQ: 0 ANSI: 2

sd 5:0:0:0: Attached scsi generic sg3 type 0

sd 5:0:0:0: [sdc] Attached SCSI removable disk

Untuk baris ini proses deteksi MMC storage (catatan:VT-18 sudah build-in MMC Reader)
kenapa hasilnya sdc ? karena di komp saya sudah ada dua hardisk sda dan sdb jadi kemungkinan
hasil ini akan berbeda di setiap komputer.
Baris di atas juga  tidak ada vendor dan product id untuk MMC storage atau CDROM sehingga saya
kesulitan jika ingin menggunakan usb_modeswitch karena perlu default vendor/product beserta
target vendor/product.

Terus gimana dong kl sudah begini? Buntu? OOH TENTU TIDAK.. :)
di eject saja semua device di atas.

#eject /dev/sr1

#eject /dev/sdc

Diteruskan dengan meloading kernel module beserta product dan vendor id ke dalam device modem.

#/sbin/modprobe usbserial vendor=0x1d09 product=0xaef4

hasilnya akan menjadi seperti dibawah ini

usb 3-2.3: USB disconnect, address 4
