> Yes, compat-wireless ships with ''CONFIG_RT2800USB_RT30XX=y'' in config.mk, but the card's VIDs aren't shown in modinfo rt2800usb when compiled, thus the module doesn't recognize the card at all. The only workaround I rustled up is the above mentioned one. 

Thats odd, in compar-wireless, it already contains the lines:

#ifdef CONFIG_RT2800USB_RT30XX
	<..snip..>
	/* Ralink */
	{ USB_DEVICE(0x148f, 0x2070), USB_DEVICE_DATA(&rt2800usb_ops) },
	{ USB_DEVICE(0x148f, 0x3070), USB_DEVICE_DATA(&rt2800usb_ops) },
	{ USB_DEVICE(0x148f, 0x3071), USB_DEVICE_DATA(&rt2800usb_ops) },
	{ USB_DEVICE(0x148f, 0x3072), USB_DEVICE_DATA(&rt2800usb_ops) },
	<..snip..>
#endif

So adding the USB ID does not need to be added.
