Ubuntu8.04 PCMCIA介面（華為EG602）EDGE上網卡安裝筆記

硬體環境：IBM T43p
操作系統：Ubuntu8.04

我的無線上網卡是華為的EG602，結果被系統（ubuntu8.04)識別成華為E220，導致無法使用。

前幾日安裝完ubuntu，成功設置好了EDGE卡並撥號上網。誰知天有不測風雲，在xp下使用分區工具刪除另外一個linux分區的時候，包括E盤在內的諸多分區都不翼而飛了，於是使用分區表工具恢復了分區，但是所有的linux分區都變成了未分區空間。

再次從裝了ubuntu后，發現系統識別的EDGE卡和上一次有些區別，此後多次從裝系統，依然無法像第一次一樣正常使用EDGE卡

原來：
插上設備的時候，多出ttyUSB0，1，2，3，4，5一系列設備

root@asia:~# dmesg |grep tty
[ 4.538995] console [tty0] enabled

現在：
較之原來缺少了USB3，4，5
[ 11.316735] console [tty0] enabled

可惜當時沒有lsusb看一下，系統把我的卡識別成什麼型號設備！

哈哈，今天終於把問題給解決了

解決方法如下：

啟動系統后，把原來系統載入的模塊刪除掉
root@ubuntu:~# rmmod airprime usbserial

把卡彈出后在插入后，奇迹出現了

root@ubuntu:~# dmesg |grep tty
[ 765.702220] usb 6-1: airprime converter now attached to ttyUSB0
[ 765.702329] usb 6-1: airprime converter now attached to ttyUSB1
[ 765.702430] usb 6-1: airprime converter now attached to ttyUSB2
[ 765.709661] usb 6-1: airprime converter now attached to ttyUSB3
[ 765.709785] usb 6-1: airprime converter now attached to ttyUSB4
[ 765.709888] usb 6-1: airprime converter now attached to ttyUSB5

直覺告訴我，問題已經迎刃而解了！

果然

哈哈，困擾我幾天的難題解決了！

居然EG602卡還是被系統識別成E220，無所謂了，反正好用了。
