in the website of rt2x00,it says the kernel 2.6.24 have alreadys contained the driver of rt73,i have download the kernel 184.108.40.206 and i also find the code of rt73 driver in drivers/net/wireless/,but in the make menuconfig i cant find any options to choose rt73,can somebody tell me how can i let the rt73 option(Ralink driver support) appear in the menuconfig,
Then you are missing some dependencies, like wireless support.
in menuconfig you must enable (in that order)
Networking support -> Wireless -> Generic IEEE 802.11 Networking Stack (mac80211)
Device Drivers -> Network device support -> Wireless LAN -> Ralink driver support -> Ralink rt2501/rt73 (USB) support
