Hi all,

I want to enable Wi-Fi on beagleboard for android using DlInk DWA
110 adapter based on Ralink chipset.

I had selected the rt2500,rt2570,rt73 drivers from "make menuconfig"
and rebuilt the kernel. By then, when booted on the board, board
detects the adpapter with wlan0 interface.

But when I tried to "up" the WiFI using command " ifconfig wlan0
up", it gives following error,

# ifconfig wlan0
up
rt73usb 1-2:1.0: firmware: requesting
rt73.bin
init: untracked pid 859
exited
phy0 -> rt2x00lib_request_firmware: Error - Failed to request
Firmware.
error: SIOCSIFFLAGS (No such file or directory)

From google arround, I found that it is related to permission problem
but could not found the solution. Can anyone please tell the issue. I
will be really grateful.
