Ok, I finally got my dlink dw140 working on dm8000 with 2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.3_DPO driver. I installed last OE firmware and OE toolchain worked. Also I set HAS_WPA_SUPPLICANT=y and HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n in config.mk. Its necessary to reboot to make usb driver working (rt5370sta.ko must be in /etc/modules) and remove/blacklist rt28* kernel modules. Attached kernel module for dm8000 kernel 3.2
