*I get this error while trying to load manually:*

I tried wit both:

and
Linux beaglebone 4.1.14-bone-rt-r17 #1 Sat Dec 12 11:34:12 UTC 2015 armv7l
GNU/Linux (BBBMINI image)
*Please note that the driver is loading OK at cold boot* , but i have to
type ifconfig -a to see it:

*But I cannot manually reload it* (ifconfig wlan0 down/up):
root@beaglebone:~# ifconfig wlan0 up
[ 512.010734] ieee80211 phy0: rt2x00lib_request_firmware: Error - Failed

* and It cannot load Hostapd* :

random: Trying to read entropy from /dev/random[ 334.613444] ieee80211
phy0: rt2x00lib_request_firmware: Error - Failed to request Firmware
The other issue is that I cannot set the country code within the kernel
with iw reg set US
so it is looping at boot with an error related to the country code:
[ 41.398481] cfg80211: Calling CRDA to update world regulatory domain
This device is working fine on my BB Black with various Kernel release and
the device is on a powered USB hub.
The iw reg set command is a little bit marginal and does not seem to works
all the time and it is required by the driver
to run on the 5 Ghz Frequency Range
Thank for any help on this
