时隔了近两年，楼主你这问题解决了没。
我也遇到类似的问题，我的是TL-WN821N V3.0无线网卡，应用在mini2440上（内核Linux2.6.32.2），当插入无线网卡时出现信息如下：
[root@Sinexcel firmware]# usb 1-1: new full speed USB device using s3c2410-ohci and address 12
usb 1-1: New USB device found, idVendor=0cf3, idProduct=7015
usb 1-1: New USB device strings: Mfr=16, Product=32, SerialNumber=48
usb 1-1: Product: UB95
usb 1-1: Manufacturer: ATHEROS
usb 1-1: SerialNumber: 12345
usb 1-1: configuration #1 chosen from 1 choice
usb 1-1: reset full speed USB device using s3c2410-ohci and address 12
usb 1-1: firmware: requesting ar9170.fw
usb 1-1: USB setup failed (-110).
ar9170usb: probe of 1-1:1.0 failed with error -110
我已在lib/firmware目录加放置了ar9170-1.fw ar9170-2.fw ar9170.fw等文件了，哪位高人能否帮我解决，不胜感激
而且我在linux配置里也添加了ATHEROS的无线网卡驱动支持。
