Ubuntu는 10.04, kernel 2.6.32-24이며 T-Login은 LG Innotek에 LM-629HUL 모델입니다.
기존에 IM-H100 (C-Motech) 모델의 경우 USB로 연결하면 /dev/ttyACM0로 연결이되기 때문에 kppp나 gnome-ppp에서 modem설정에서 ttyACM0로 설정을 하면 동작 됩니다.
하지만 C-Motech의 CHU-628S나 LG Innotek의 LM-629HUL의 경우 usb-modeswitch를 통해 mode를 변경해 줘야 합니다.
usb-modeswitch 1.1.3
libusb-0.1.12
컴파일하여 설치 합니다.
usb를 연결 후 lsusb 실행하면 아래와 같이 17d4:1004가 생깁니다.

Window에서도 PID가 1004로 붙고 driver 설치 후 PID가 00c9으로 변경되는 것을 확인 할 수 있습니다. 아마도 linux에서도 정상 동작 시키려면 1004가 00c9이 되면 되겠죠.
그래서 usb-modeswitch가 필요한 것입니다.
하지만 usb-modeswitch-data-20100707.tar.bz2 여기에는 LM-629HUL 모델 script가 없습니다.
usb-modeswitch-data-20100707를 설치 하셨다면 /etc/usb_modeswitch.d/에 1d74:1004로 아래의 파일을 만듭니다.
########################################################
# LG Innotek LM-629HUL
DefaultVendor=0x1d74
DefaultProduct=0x1004
TargetClass=0xff
CheckSuccess=20
MessageContent="55534243b82e238c240000008000081c020000000000000000000000000000"
위에 값을 어떻게 찾을 것인가가 최대의 문제 였습니다.
C-Motech CHU-629S가 제일 비슷하다고 판단하였습니다.
16d8:700a를 복사 하였고 DefaultVendor와 DefaultProduct는 lsusb의 값이 1d74그리고 1004를 입력 한다.
TargetClass의 경우 필요한지 판단할 수 없지만 Windows에서 드라이버 등록 정보를 보면 Class가 0xff로 되어 있는 부분을 확인 할 수 있다.
그리고 MessageContent 이 값은 usb-modeswitch의 설명 처럼 SniffUSB를 이용하여 logging을 할 수 있지만 plug/unplug를 해도 엄청난 line의 log가 생깁니다.
일단 UsbSnoop.log을 봅시다.
어떤 값을 MessageContent에 넣어야 할지 판단이 되지 않는다.
위에 사이트에 보면 IRP_MN_SURPRISE_REMOVAL를 검색해 보면 될거란 힌트를 얻을 수 있습니다.
아래의 log는 연결하고자 하는 pc에서 얻는 값이다.

위와 같이 Product id가 바뀌어 있다.
이제 usbserial 드라이버를 올릴 차례입니다.
sudo lsmod usbserial vendor=0x1d74 product=0x00c9
그럼 /dev/ttyUSB 노드가 생성됩니다.
그후 kppp
오늘은 피곤해서 여기까지 낼 다시 작성하겠습니다.
