Hello Ivo, all,

I just want to report that we successfully built and configured DWA-140
(rev B3, RT5370 chip) USB-WiFi in access point mode. For this, we built
vcompat-wireless modules and hostapd and lbnl (required by hostapd).

Our target is the LPC1788 (ARM Cortex-M3 SOC) running Linux 2.6.33,
with USB support.

Our toolchain combo is CodeSourcery arm-2010q1, with uClibc modified to
support clone() and linuxthreads.

Thank you for your comments.

Regards,
Sergei Poselenov, Emcraft Systems
