如何在linux(内核2.6.x)下驱动USB ADSL


  1.准备工作
  现在确认你有一支Conexant USB ADSL的Modem和以下文件,(如果您没有备齐这些东西,下面的工作将无法进行)
  
  引用:
  cxacru.tar.bz2 rp-pppoe-3.5.tar.gz Kernel-2.6.x patch-2.6.X_date_accessrunner.gz
  
  说明:
  
  其中cxacru.tar.bz2(要在此处下载我已经打好补丁的文件)是USB ADSL的驱动程序文件源代码包
  
  rp-pppoe-3.5.tar.gz(或更高版本)是pppoe的拨号程序源代码包
  
  Kernel-2.6.x是Kernel的源代码包
  
  patch-2.6.X_date_accessrunner.gz是内核的补丁文件
  
  确定备齐以上文件后就可以进行下面的工作了
  
  2.开始安装
  首先将设备联结好
  
  2.1给内核打补丁并编译内核
  
  解压内核包把patch-2.6.X_date_accessrunner.gz拷贝到内核目录的上级目录
  
  执行 代码:
  gunzip -c patch-2.6.x_YYYYMMDD_accessrunner.gz | patch -p1
  
  如果你的Kernel已经有如下支持(可以在Kernel的.config文件中查找到)就不必重新编译
  代码:
  
  Code maturity level options
  
  [*] Prompt for development and/or incomplete code/drivers
  
  Loadable module support
  
  [*] Enable loadable module support
  
  [*] Set version information on all module symbols
  
  [*] Kernel module loader
  
  Networking options
  
  < *> Packet socket
  
  < *> Unix domain sockets
  
  [*] TCP/IP networking
  
  [*] Asynchronous Transfer Mode (ATM)
  
  USB support
  
  < *> Support for USB
  
  [*] Preliminary USB device filesystem
  
  UHCI
  
  OHCI
  
  Alcatel Speedtouch USB support (USB_SPEEDTOUCH)
    
  Networking options
  
  [*] Asynchronous Transfer Mode (ATM)
  
  [*] Classical IP over ATM
  
  
  Networking options
  
  [M] RFC1483/2684 Bridged protocols
  
  Network Device Support
  
  PPP (point-to-point protocol) support
  
  PPP Deflate compression
  
  PPP over Ethernet (EXPERIMENTAL)
  
  Network Device Support
  
  PPP (point-to-point protocol) support
  
  PPP Deflate compression
  
  PPP over ATM
  
   Processor type and features
  
  [ ] Symmetric multi-processing support
  
  Cryptographic API (CRYPTO)
  
  CRC32c CRC algorithm (CRYPTO_CRC32C)
  
  Library routines
  
  CRC32c (Castagnoli, et al) Cyclic Redundancy-Check (LIBCRC32C)
  
  设置好后 make 、make modules 、make modules_install、make install、reboot
  
  2.2编译驱动和拨号程序
  
  解压cxacru.tar.bz2,ln /内核源代码目录 /usr/linux -s
  
  然后在源代码目录中make,
  
  解压rp-pppoe-3.5.tar.gz,在其目录中执行./go 如果你用X 就可以用./go-gui
  
  设置好你的拨号程序,要注意的是在填写设备的时候要填写nas0
  
  nas0是驱动程序虚拟出来的USB Modem
  
  2.3设置协议
  
  编辑/etc/cxacru文件,像这个样子:
  代码:
  
  #
  # Config file for Conexant AccessRunner
  #
  
  # Driver mode
  DRIVER_MODE=1 # 1 = normal, 2 = debug, 3 = normal+max speed (without ask adsl status), 4 = debug+max speed (without ask adsl status)
  
  # Protocol
  PROTOCOL_MODE=4 # 1 = RFC1483/2684 routed, 2 = PPP over ATM (pppoa), 3 = RFC1483/2684 bridged, 4 = PPP over Ethernet (pppoe)
  
  # Paths
  BINARY_PATH="/usr/sbin"
  ATM_PATH=""
  
  # ADSL
  # if OPEN_MODE is blank then cxload uses default mode acoording VID & PID
  # Values for OPEN_MODE are:
  #  0 = auto selection, G.Handshake
  #  1 = auto selection, T1.413
  #  2 = G.Handshake
  #  3 = ANSI T1.413
  #  4 = ITU-T G.992.1 (G.DMT)
  #  5 = ITU-T G.992.2 (G.LITE)
  OPEN_MODE=4
  
  # ATM
  VPI=0
  VCI=33
  
  # Specific for RFC1483/2684 routed/bridged
  # if IP_ADDRESS is blank in bridged mode then it uses DHCP to get IP
  IP_ADDRESS=
  NETMASK=255.255.255.255
  GATEWAY=
  
  需要更改的是# Protocol # ADSL # ATM
  
  如果你用的是RFC1483/2684协议还要设置# Specific for RFC1483/2684 routed/bridged
  
  PPPOE和PPPOA的用户只要修改# Protocol # ADSL # ATM 这3项就可以了
  
  3.拨号
  在终端下输入cxstart.sh建立连接 cxstop.sh断掉连接
  
  用ifconfig检查一下你是否已经连上了,像这个样子:
  代码:
  
  [root@Love root]# ifconfig
  lo    Link encap:Local Loopback
       inet addr:127.0.0.1 Mask:255.0.0.0
       inet6 addr: ::1/128 Scope:Host
