小弟試了大大的連結去try，仍然無法使用q101上網。
小弟try的方法如下：

Step(1)
Download usb_modeswitch-1.0.2.tar.bz2
下載的網址如下：http://www.draisberghof.de/usb_modeswitch/usb_modeswitch-1.0.2.tar.bz2

下載完畢解壓縮後桌面上會有一個usb_modeswitch-1.0.2的資料匣 。
我把該資料匣裡的usb_modeswitch 這個檔 copy 到 /bin 下
接著又把usb_modeswitch.conf 這個檔 copy 到 /etc下


Step(2)
安裝 libusb
apt-get install libusb-dev

Step(3)
安裝 wvdial(Ubuntu 9.04預設是沒有安裝)
apt-get install wvdial


Step(4)
編寫script
1 vim mytest.sh
2 貼上以下的內容
#--------------------------------------------------------
#!/bin/sh
usbPort=`lsusb | grep Quanta | cut -d ' ' -f 2 | sed 's/0//g'`
echo "USB裝置所在位置：usb$usbPort"
usb_modeswitch
echo "USB裝置ID變更"
echo " "
sleep 3
echo "停止USB隨身裝置"
echo " "
echo "suspend" > /sys/bus/usb/devices/usb$usbPort/$usbPort-1/power/level
echo "鎖定USB裝置ID"
echo " "
modprobe usbserial vendor=0x0408 product=0xea02
sleep 8
echo "重新搜尋 Q101 所在 USB 位置....並設定 /etc/wvdial"

wvdialconf

echo "啟動 wvdial 進行撥號...."

echo " "
sleep 5
wvdial &
#------------------------------------------------------------------------------
3 chmod +x mytest.sh

Step(5)
執行mytest.sh
./mytest.sh
--------------------------
執行mytest.sh後，仍然無法使用台灣大哥大的q101無線網卡上網。
把執行的錯誤訊息以上如下：

root@ubuntu:/home/james/桌面/usb_modeswitch-1.0.2# ./mytest.sh
USB裝置所在位置：usb4

Sorry, no modem was detected! Is it in use by another program?
Did you configure it properly with setserial?
