如何移植compat-wireless的usb无线网卡驱动到FL2440 arm开发板上？
我用的是 迅捷FW150UD usb无线网卡，迅捷FW150UD的控制芯片好像是AR9271，开发板用的是FL2440，开发板上的linux内核版本是2.6.28.7，文件系统qtopia-2.2.0，交叉编译环境用的是cross-3.4.1，compat-wireless用的是compat-wireless-2011-01-07。
执行./scripts/driver-select脚本选择ath9k_htc
再执行make KLIB=/home/arm/linux-2.6.28.7 KLIB_BUILD=/home/arm/linux-2.6.28.7
编译完成后
compat-wireless中modules.order内容：

无线网卡插上后只提示

但无线网卡的指示灯不亮。

也不知道内核的那些模块是需要加载的
基本情况就是这样，但加载compat-wireless中要求的模块后无线网卡不能识别。还有ar9271.fw已经放到 /bin/ 文件夹下了
希望有知道怎么解决的前来指点一下。
[解决办法]
内核没有配置好吧
[解决办法]
刚才弄了一下，成功了！。
内核配置
Build ATH9K_HTC driver:
1. Kernel config:
Please make sure your current kernel config has following settings:
CONFIG_NET_SCHED=y
CONFIG_CFG80211=m
CONFIG_MAC80211=m
CONFIG_RFKILL=m
CONFIG_WLAN_80211=y
# CONFIG_ATH9K is not set
固件是在 /lib/firmware/下的 ， 名字叫 htc_9271.fw
http://my.oschina.net/u/147624/blog/56052
插入模块：
insmod compat.ko
insmod compat_firmware_class.ko
insmod rfkill_backport.ko
insmod cfg80211.ko
insmod mac80211.ko
insmod ath.ko
insmod ath9k_hw.ko
insmod ath9k_common.ko
insmod ath9k_htc.ko
我编译出来的模块没有kfifo.ko
插入USB网卡显示：
