3G無線上網卡在Linux下的使用

首先，這是一個比較簡單的問題,我是在Linux下和Windows下作了一個對比

1，Windows下第一次插入該貓的時候，會以一個usb外接存儲設備顯示出來，並且看上去是一個CD-ROM的Media設備，當在Windows下安裝完電信的撥號程序以後，這個CDROM的設備就不見了，然後打開Windows的超級終端，會看到三個新的串口設備

2，在Linux下，無論什麼時候插入該貓的時候，都會是一個usb外接存儲設備顯示出來，並且看上去是一個CD-ROM的Media設備

然後通過cat /proc/kmsg獲得相關調試信息，我使用的kernel是加了kernel hacking選項的，也就是說，打印信息會多點，方便調試，看到如下信息：

  99. .........................
  100. ^C

然後ls /dev就可以看到一些關鍵設備，比如sr0

  1. [root@localhost liuqi]# ls /dev/
  2. 0:0:0:0 dsp loop4 pcmC0D0c random stdout tty28 tty50 usb3 vcs1
  3. adsp event0 loop5 pcmC0D0p rfkill systty tty29 tty51 usb4 vcs2

  17. cpu0 hpet mouse0 ram15 sequencer tty19 tty41 tty7 usbmon0 zero
  18. cpu1 hwC0D0 mouse1 ram2 sequencer2 tty2 tty42 tty8 usbmon1
  19. cpu_dma_latency input msr0 ram3 sg0 tty20 tty43 tty9 usbmon2
  20. cuse kmem msr1 ram4 sg1 tty21 tty44 ttyS0 usbmon3
  21. device-mapper kmsg net ram5 shm tty22 tty45 ttyS1 usbmon4
  22. disk log network_latency ram6 snapshot tty23 tty46 ttyS2 usbmon5
  23. dlm-control loop0 network_throughput ram7 snd tty24 tty47 ttyS3 usbmon6
  24. dlm-monitor loop1 null ram8 sr0 tty25 tty48 urandom usbmon7
  25. dlm_plock loop2 ocfs2_control ram9 stderr tty26 tty49 usb1 usbmon8
  26. dri loop3 oldmem ramdisk stdin tty27 tty5 usb2 vcs

然後lsusb可以看到我們的新usb的相關信息

  1. [root@localhost liuqi]# lsusb
  2. Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
  3. Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  4. Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
  5. Bus 006 Device 004: ID 05c6:2001 Qualcomm, Inc.
  6. Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
  7. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  8. Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
  9. Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
  10. Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

可以看出來，關鍵的是：

  1. Bus 006 Device 004: ID 05c6:2001 Qualcomm, Inc.

可以看到，其

  1. Vendor: 05c6 ProductID:2001

其實這個就是我們剛才看到的/dev/sr0相對應的usb的信息

可以說，之前說過的都等於白說，僅僅是一些信息的獲得，經過觀察可以看出來，在Windows下安裝完撥號程序以後，就看不到cdrom了，這個時候就可以看到串口設備了，那麼可以總結，應該是有一個將cdrom給彈出來了，這個時候使用了一下如下命令

  1. eject /dev/sr0

這樣就把Media彈出了，然後再lsusb看一下


  1. [root@localhost liuqi]# lsusb
  2. Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
  3. Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  4. Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
  5. Bus 006 Device 005: ID 1e0e:ce16
  6. Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
  7. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  8. Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
  9. Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
  10. Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

這回好了，看到結果了，

  1. Bus 006 Device 005: ID 1e0e:ce16

結果就是，這個usb的VendorID: 1e0e ProductID:ce16

看了一下kernel的源代碼，這個Vendorid和ProductID是支持的
我的kernel是比較新的，這個驅動對應的patch應該還是國內的某兄台提交的，所以，支持是沒有問題的
然後看一下/dev/下的設備

  1. [root@localhost liuqi]# ls /dev/
  2. 0:0:0:0 dri loop0 msr1 ram15 sda9 tty14 tty34 tty54 usb1 usbmon5
  3. adsp dsp loop1 net ram2 sdb tty15 tty35 tty55 usb2 usbmon6

  5. audio event1 loop3 network_throughput ram4 sequencer tty17 tty37 tty57 usb4 usbmon8
  6. bsg event2 loop4 null ram5 sequencer2 tty18 tty38 tty58 usb5 vcs
  7. btrfs-control event3 loop5 ocfs2_control ram6 sg0 tty19 tty39 tty59 usb6 vcs1
  8. bus event4 loop6 oldmem ram7 sg1 tty2 tty4 tty6 usb7 vcs2

  23. dlm_plock log msr0 ram14 sda8 tty13 tty33 tty53 urandom usbmon4
  24. [root@localhost liuqi]#

多了三個串口設備，這樣就對了，接下來就可以使用串口設備了

使用minicom先試試哪個串口好用




  1. +CSQ:31, 99

  3. OK

  5. +CGMR: P1.0 DLink_DWM-162-U5_V1.0

  7. OK

  9. ^HRSSILVL:99

  11. ^HRSSILVL:80

通過AT指令可以看出來，可以玩了，接下來設置一下conf就可以了，這個在網上應該可以找到各種方法來連接，其實都是at指令來配一下而已
