[Tomato] 3G 測試
以下是在Tomato(USB版)的測試紀錄, 測試原則請先參閱前述DD-WRT(3G版), CDMA@wifi, Lly.
機型: 華碩WL-520gU
3G modem: 華為 E220
韌體:
Tomato USB v1.25.8634 ND USB Ext (英文)
Tomato RAF v1.23.8624 -RAF ND USB Std (正體中文)
1.) E220 偵測
若直接將E220接在WL-520gU的USB port, 無法被偵測到. 必須外接USB Hub, 將E220接到USB Hub, 才能偵測到.
v1.23, v1.25
dmesg
hub.c: new USB device 00:03.1-1.1, assigned address 3
scsi0 : SCSI emulation for USB Mass Storage devices
Vendor: HUAWEI Model: Mass Storage Rev: 2.31
Type: CD-ROM ANSI SCSI revision: 02
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 3. Host: 0
2.) usbserial.o
2-1) v1.23
2-1-1) CDMA@wifi
# insmod usbserial.o
insmod: unresolved symbol usb_deregister_devpath
2-1-2) http://www.jamdev.co.uk/wiki/static/pri … sbserial.o
# insmod usbserial.o
dmesg
usb.c: registered new driver serial
usbserial.c: USB Serial support registered for Generic
usbserial.c: USB Serial Driver core v1.4
嗯, 這個可以. 或許還可找OpenWrt kmod試試看.
2-2) v1.25
2-2-1) CDMA@wifi
# insmod usbserial.o
insmod: unresolved symbol usb_deregister_devpath
2-2-2) Lly
# insmod usbserial.o
insmod: unresolved symbol tty_ldisc_ref
2-2-3) http://www.jamdev.co.uk/wiki/static/pri … sbserial.o
# insmod usbserial.o
Segmentation fault
看來, 只能再看機緣, 試試OpenWrt kmod. 所以, V1.25測試到此.
3.) modem.o, option.o
3-1) CDMA@wifi
# insmod modem.o
dmesg
Warning: loading modem will taint the kernel: non-GPL license - PRIVATE
See http://www.tux.org/lkml/#export-tainted for information about tainted modules
modem.c: GSM/CDMA modem driver v0.1
3-2) Lly
# insmod option.o
dmesg
usbserial.c: USB Serial support registered for Option GSM modem
option.c: USB Driver for GSM modems: v0.7.2a
看起來, modem.o或option.o都能載入, 但檢查dmesg, 卻有致命訊息.

測試尚未成功, 等待有3G modem的網友接力測試.
