I'm trying to connect my L138 EMV to wireless router using USB wifi dongle using DVSDK_4.03 04_03_00_06.
using this forum post as road map

I'm now able to connect EVM with D-link DWA-160 A2 adapter attached to USB1.1 port to wireless network, but with 2.0 port there is problem.
when wifi adapter attached to 2.0 port it is enumerated fine, firmware downloaded too. then I set network parameters and up connection:
root@arago:~# iwconfig wlan0 mode managed
root@arago:~# iwconfig wlan0 essid "D-link"
root@arago:~# iwconfig wlan0 key 1234512345
root@arago:~# iwconfig wlan0 channel auto

everything looks ok until dhcp procedure:

it seems wifi adapter hangs. I was trying ar9170 and carl9170-1 firmwares and both Atheros and Linux Community drivers integrated in kernel. for community driver log provided above. here network fails, but adapter successfully restarted. with Atheros driver enabled in kernel and ar9170.fw firmware I have to manually replug dongle to make it enumerated again.
as with 1.1 port everything works fine the question is what's wrong with USB 2.0?
I'w attached my .config file for kernel 4034.config.zip
Thanks,
Dmitriy.
