Ralink RT3573 / ASUS USB-N66: run0: could not load 8051 microcode

[Alex Deiter]

Hello Kevin,

I'm trying to get ASUS USB-N66 USB wifi adapter working with FreeBSD
11.0-CURRENT #0 r261642 amd64.
I plug the adapter and it seems to be recognized:

#dmesg
run0: <1.0> on usbus1
run0: MAC/BBP RT3593 (rev 0x0402), RF RT3053 (MIMO 3T3R), address
30:85:a9:f4:52:bd
run0: 11a rates: 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps
run0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
run0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps
24Mbps 36Mbps 48Mbps 54Mbps

I can create the wlan device:

# ifconfig wlan0
wlan0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether 30:85:a9:f4:52:bd

But got an error when interface is up:

# ifconfig wlan0 up scan

I plug in the same adapter to a laptop with Windows 7, it successfully
shows the nearby access points and allows me to connect to one, so the
adapter is not broken. Any ideas for further troubleshooting are welcome.

Thank you!
