Step1: Download driver DPO_RT3070_LinuxSTA_V2.3.0.4_20100604.tar.gz

//un-compress
Step2: $tar -xzvf DPO_RT3070_LinuxSTA_V2.3.0.4_20100604.tar.gz

//change folder
Step3: $cd DPO_RT3070_LinuxSTA_V2.3.0.4_20100604


//get root permission
Step4: $su


//compile your driver
Step5: #make

//Create new folder
Step6: #mkdir /etc/Wireless/RT2870STA

//Copy file to the new folder
Step7: #cp RT2870STA.dat /etc/Wireless/RT2870STA/.

Notice!!

Build Fail, If kernel version is 2.6.35,

=====================================================

make[2]: *** [/home/pierre/DPO_RT3070_LinuxSTA_V2.3.0.4_20100604/os/linux/../../common/cmm_mac_usb.o] Error 1

make[1]: *** [_module_/home/pierre/DPO_RT3070_LinuxSTA_V2.3.0.4_20100604/os/linux] Error 2

make[1]: Leaving directory `/usr/src/linux-headers-2.6.35-28-generic'

make: *** [LINUX] Error 2

=====================================================

You can check kernel version 

$uname -a

Root Cause：

After 2.6.35 version,

Function
usb_buffer_alloc => usb_alloc_coherent
usb_buffer_free  => usb_free_coherent

Solution:

Two files need to modify.

1. include/os/rt_linux.h

i.

#define RTUSB_URB_ALLOC_BUFFER(pUsb_Dev, BufSize, pDma_addr) usb_buffer_alloc(pUsb_Dev, BufSize, GFP_ATOMIC, pDma_addr)

=>

#define RTUSB_URB_ALLOC_BUFFER(pUsb_Dev, BufSize, pDma_addr) usb_alloc_coherent(pUsb_Dev, BufSize, GFP_ATOMIC, pDma_addr)

ii.

 #define RTUSB_URB_FREE_BUFFER(pUsb_Dev, BufSize, pTransferBuf, Dma_addr) usb_buffer_free(pUsb_Dev, BufSize, pTransferBuf, Dma_addr)

=>

#define RTUSB_URB_FREE_BUFFER(pUsb_Dev, BufSize, pTransferBuf, Dma_addr) usb_free_coherent(pUsb_Dev, BufSize, pTransferBuf, Dma_addr)

2. /os/linux/rt_usb_util.c

i.

  return usb_buffer_alloc(dev, size, mem_flags, dma);

=>

return usb_alloc_coherent(dev, size, mem_flags, dma);

ii.

  usb_buffer_free(dev, size, addr, dma);

=>

usb_free_coherent(dev, size, addr, dma);

Finally, Re-compile
