I'm trying to use USB WiFi dongle RT3370USB on AM17x.
RT3370USB WiFi dongle is mounted on the AM17x evaluation module (EVM), I am monitoring the log data on the PC via RS232C from EVM.
I have an initialization problem when I make the dongle awake by ifconfig command.
At first I compiled the wifi driver for ARM processor and made the loadable module(rt3370sta.ko)
Then, I could install the module on AM17x EVM correctly. And I sent the command
[ifconfig ra0 up] to enable the WiFi module. But the following error massages appeared on the display.

-------------------------------------
Though I sent the command [ifconfig ra0 up] again, the same above mentioned error
messages appeared. And then, I sent the command [ifconfig ra0 up] again. I eventually could enable the WiFi module. This behavior was very strange. The log is the following.

I could also confirm same problem with RT3070USB on AM17x.
RT3070USB is similar device to RT3370USB.
Anyway, I would like to fix this problem.
Could anyone kindly give a solution?
