Ubuntu8.04 PCMCIA接口（华为EG602）EDGE上网卡安装笔记

asia_ji

硬件环境：IBM T43p
操作系统：Ubuntu8.04



我的无线上网卡是华为的EG602，结果被系统（ubuntu8.04)识别成华为E220，导致无法使用。

前几日安装完ubuntu，成功设置好了EDGE卡并拨号上网。谁知天有不测风云，在xp下使用分区工具删除另外一个linux分区的时候，包括E盘在内的诸多分区都不翼而飞了，于是使用分区表工具恢复了分区，但是所有的linux分区都变成了未分区空间。
再次从装了ubuntu后，发现系统识别的EDGE卡和上一次有些区别，此后多次从装系统，依然无法像第一次一样正常使用EDGE卡
原来：
插上设备的时候，多出ttyUSB0，1，2，3，4，5一系列设备
root@asia:~# dmesg |grep tty
[ 4.538995] console [tty0] enabled

现在：
较之原来缺少了USB3，4，5
[ 11.316735] console [tty0] enabled
[ 13.125485] 00:0a: ttyS0 at I/O 0x3f8 (irq = 4) is a NS16550A

可惜当时没有lsusb看一下，系统把我的卡识别成什么型号设备！！



哈哈，今天终于把问题给解决了
解决方法如下：
启动系统后，把原来系统加载的模块删除掉
root@ubuntu:~# rmmod airprime usbserial
把卡弹出后在插入后，奇迹出现了
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
直觉告诉我，问题已经迎刃而解了！
果然

哈哈，困扰我几天的难题解决了！

晕，居然EG602卡还是被系统识别成E220，无所谓了，反正好用了！！
