Hallo,

I recently bought an Asus USB-N53 Dual Band Wireless Network Adapter and 
noticed that I have to enable CONFIG_RT2800USB_UNKNOWN to get it working. With 
this option enabled everything is working fine as far as I have tested.

So I'd line to get things right and move this device out of 
CONFIG_RT2800USB_UNKNOWN to where it belongs.


Here is the information I have about this device, feel tree to ask if you need 
anything addition.

Asus Website about the device:
http://www.asus.com/Networks/Wireless_Adapters/USBN53/

output of lsusb:
Bus 005 Device 013: ID 0b05:179d ASUSTek Computer, Inc. USB-N53 802.11abgn 
Network Adapter [Ralink RT3572]

output of dmesg:
usb 5-6: new high-speed USB device number 13 using ehci_hcd
usb 5-6: New USB device found, idVendor=0b05, idProduct=179d
usb 5-6: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 5-6: Product: 802.11 n WLAN
usb 5-6: Manufacturer: Ralink
usb 5-6: SerialNumber: 1.0
usb 5-6: reset high-speed USB device number 13 using ehci_hcd
ieee80211 phy6: Selected rate control algorithm 'minstrel_ht'
Registered led device: rt2800usb-phy6::radio
Registered led device: rt2800usb-phy6::assoc
Registered led device: rt2800usb-phy6::quality


So according to lsusb this is a RT3572 device, which does also match with the 
chip description from ralink: 
http://www.ralinktech.com/en/02_products/product.php?sn=1009

I suggest moving the device to the CONFIG_RT2800USB_RT35XX section in 
rt2800usb.c, see attached patch.
