phy0 -> rt2500usb_init_eeprom: Error - Invalid RT chipset detected.

我是用友善官方最新的内核image(2.6.32.2),  插上TL-WN321G+到mini2440不能成功侦测, 但插上Windows XP是能正常使用, 所以确定不是硬件问题.

看到报错"phy0 -> rt2500usb_init_eeprom: Error - Invalid RT chipset detected."  大家知否是Linux内核问题吗?

这是内核中驱动(drivers/net/wireless/rt2x00/rt2500usb.c)的部分源代码。红色部分就是你遇到的错误。看起来和芯片的硬件版本有关：

放弃使用TL-WN321G, 转用了TL-WN322G.

咨询过rt73 driver (rt2x00)的开发团体, Ralink在rt73及rt2500有部分数组相同, 刚巧我的TL-WN321G就是用 USB_DEVICE(0x148f, 0x2573), 所以被错唔认为rt2500, 所以导致驱动安装失败. 可惜的说那个patch被reject了, 开发团体建议我自行修改. 我打算索性直接用universal programmer硬改无线网卡上的EEPROM的 USB Device ID.

好，这是解决问题的正确方法

我也是一样的问题中……
