因工作需要,最近为笔记本配备了CDMA无线上网卡,从此网络无处不在~~~~
偶使用的是联通 CDMA 1X 世界风 USB接口的无线网卡,很小,比普通U盘宽一点,此网卡估计是联通找厂商专门OEM的,采用的是美国 Silicon Labs 生产的 CP2101/CP2102 芯片,在 Linux 下驱动很简单。
CP2102简介:该芯片的功能是实现USB 和UART格式间数据的转换. CP2102是全新的UART转USB的单芯片解决方案。该芯片集成了一个符合USB2.0标准的全速功能控制器、EEPROM、缓冲器、和带有调制解调器
对于Linux 2.6.18 的内核,需要配置的地方如下:
1. USB 支持肯定是要的
Device Drivers -> USB Support ->
<M> Support for Host-side USB
[*] USB device filesystem
<M> EHCI HCD (USB 2.0) support
<M> OHCI HCD support
<M> UHCI HCD (most Intel and VIA) support
<M> USB Modem (CDC ACM) support
USB Serial Converter support --->
<M> USB Serial Converter support
[*] USB Generic Serial Driver
<M> USB CP2101 UART Bridge Controller
<M> USB driver for GSM and CDMA modems
如果使用其他芯片的无线网卡,在这里将它们选上
2. PPP 模块
Device Drivers -> Network device support -->
<M> PPP (point-to-point protocol) support
[*] PPP multilink support (EXPERIMENTAL)
[*] PPP filtering
<M> PPP support for async serial ports
<M> PPP support for sync tty ports
<M> PPP Deflate compression
<M> PPP BSD-Compress compression
<M> PPP MPPE compression (encryption) (EXPERIMENTAL)
<M> PPP over Ethernet (EXPERIMENTAL) ~
