[AsteriskBrasil] Modem Huawei E303C No asterisk !!

[Alexandre Correa]

Depois de algumas horas estudando o processo do chan_dongle e
usb_modeswitch, consegui fazer funcionar com E303C ...

Meu uso será apenas para SMS, então não preocupei com firmware para liberar
a voz (mesmo porque não achei, se alguem tiver, poste o link !!).

Comprei um modem Huawei E303C (Nextel) para usar em uma RaspBerry Pi com a
distro raspbx !!

Ao plugar o modem, é reconhecido como CD-ROM (codigo usb 12d1:1f01)

ou em alguns casos, como uma interface ethernet (codigo usb 12d1:14db)

Este modem funciona em 3 modos:

12d1:1f01 = CD-ROM
12d1:14db = cdc_ethernet (alguns esse modo é o serial)
12d1:1442 ou 1001 = modo serial

usando o usb_modeswitch para 'trocar' o modo do modem, primeiro criei
algumas entradas no arquivo

/lib/udev/rules.d/40-usb_modeswitch.rules

que veio no usb_modeswitch da distro (talvez nao seja necessario):

---
# Huawei E303C - Nextel
ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="14db", RUN+="usb_modeswitch
'%b/%k'"

# Huawei E303C - Nextel
ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1442", RUN+="usb_modeswitch
'%b/%k'"
---

e depois no /usr/share/usb_modeswitch/ criei o arquivo (com este exato nome)

12d1:1f01

com o conteudo:

# Huawei E303
DefaultVendor= 0x12d1
DefaultProduct= 0x1f01
TargetVendor= 0x12d1
TargetProduct= 0x1442
#CDC Ethernet
#MessageContent="55534243123456780000000000000011062000000100000000000000000000"
