The driver won't install automatically as of right now, but it's not too bad to get it to work. You'll have to compile the drivers from Ralink, so make sure you have build-essential, linux-headers, and all that good stuff.
- Download RT3572USB from http://www.ralinktech.com/en/04_support/license.php?sn=5017
Change to the directory you downloaded to and run
tar -C . -xf 2011_0427_RT3572_Linux_STA_v2.5.0.0.DPO.bz2
Change to the new directory (2011_0427_RT3572_Linux_STA_v2.5.0.0.DPO).
Change HAS_WPA_SUPPLICANT and HAS_NATIVE_WPA_SUPPLICANT_SUPPORT to 'y' in the config.mk file:
sed -ir -e 's/^HAS_WPA_SUPPLICANT=n/HAS_WPA_SUPPLICANT=y/' -e 's/^HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n/HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y/' ./os/linux/config.mk
Add you Vendor and Product ID to the RT2870 supported list:
sed -ir -e 's!^#endif // RT2870 //! {USB_DEVICE(0x0B05,0x179D)}, /* Asus USB-N53 */\n#endif // RT2870 //!' ./common/rtusb_dev_id.c
Update some function names:
sed -ir -e 's/\tusb_buffer_alloc/\tusb_alloc_coherent/' -e 's/\tusb_buffer_free/\tusb_free_coherent/' include/os/rt_linux.h
Install the module:
make && sudo make install
Create a modprobe.d config file to make sure the modules load:
sudo su -c "echo -e 'alias ra0 rt3572sta\nblacklist rt2800usb' > /etc/modprobe.d/rt3572sta.conf"
Now load the module and it should work (did for me):
sudo modprobe ra0
