This is an offer to test modifications to if_run with the ASUS USB-N13 more that it is a bug report.

if_run seems like the place to support the ASUS USB-N13 USB 802.11 b/g/n.
It recognizes it if modified:

--- if_run.c    (revision 203482)
+++ if_run.c    (working copy)

     { USB_VP(USB_VENDOR_AZUREWAVE,     USB_PRODUCT_AZUREWAVE_RT2870_2) },

It then shows:
run0: MAC/BBP RT3071 (rev 0x0211) RF RT3022 (MIMO 2T2R)...
run0: loading RT3071 firmware

"ifconfig run0 up" results in a panic (page fault) at run_stop+0x5f.
