Hello,
I am trying to make work a TPlink TL WN725N NANO, that have a chip RTL8188CUS 
the adaptor works on 11-STABLE  but not on 12-CURRENT. I put some traces in the
code, it finds the adaptor, but does NOT call the firmware-get code
the code calls ieee80211_ifattach from start to return but the interface DOES
Not show wlan0  the word LZT is a "TRACE"  I put on the code that shows the
function and the source line
Note that the attach code is called, than the ieee80211_ifattach is also colled
and exit but the interface wlan0 does not show available.
Any help would be very welcome. as I need to make an access point using the
device 

some files:
/boot/loader.conf
legal.realtek.license_ack=1


===========================
dmesg after iserting the device:
