Insmod RTMP error

Hi I am still new to porting wifi drivers, and I am not sure if I posted this at the correct section. Since I am a newbie..

I am currently porting Ralink RT5370 driver, no problem with the compilation but when I execute insmod operation I got a lot of errors regarding RTMP which I have no idea where and what to fix.

this is a part of the error I got
rt5370sta: Unknown symbol rausb_buffer_free
rt5370sta: Unknown symbol RtmpOsFreeSpinLock
rt5370sta: Unknown symbol RtmpOsPktHeadBufExtend
rt5370sta: Unknown symbol RtmpOSTaskNotifyToExit
rt5370sta: Unknown symbol RtmpOsGetNetDevName
rt5370sta: Unknown symbol RtmpOsHtonl
rt5370sta: Unknown symbol RtmpOsAtomicInterlockedExchange
rt5370sta: Unknown symbol RtmpUtilInit
rt5370sta: Unknown symbol RtmpOSTaskInit
rt5370sta: Unknown symbol RtmpOsAtomicInit

insmod: can't insert '/home/rt5370sta.ko': unknown symbol in module or invalid parameter
Based on the some forum that I've read, adding the MODULE_LICENSE("GPL") is one of the solution.

I did add it inside usb_main_dev.c and recompile but I still get the same errors.

If anybody has any idea , please....

these errors were related to license issues and the new code structure of the current code that I have.

I had the same problem with Tenda W311M usb wifi, chinese crap. I had to debug the source code in the same way: correct license declarations. I did:

1) "grep MODULE_LICENSE" in os/linux/
2) there were 2 places found; I moved the license declarations out of ifdef's, so that they're always active - this helped.

Plus, I used these tips by chili555: - I don't know if this was important.
And I modified "" in 2 places ("y" instead of "n"), according to the readme (wpa_supplicant).

Note that so-called "manual" that came with Tenda was talking about different chipset, rt2870, not rt5370. And in general everything in this manual was either incorrect or outdated. Crap.
