There is a misunderstanding. The log was a QUOTE of YOUR post using DM520 and not my log. Clearly I did the same on my dm800se and the result is:

Code:
root@dm800se:~# opkg list | grep rt5572sta
kernel-module-rt5572sta - 2.6.1.3-r0 - Ralink 2870/3070/8070/3370/3572/5370/5372/5572 v2.6.1.3
kernel-module-rt5572sta-3.2-dm800se - 2.6.1.3-r0 - rt5572sta kernel module
kernel-module-rt5572sta-dbg - 2.6.1.3-r0 - Ralink 2870/3070/8070/3370/3572/5370/5372/5572 v2.6.1.3 - Debugging files
kernel-module-rt5572sta-dev - 2.6.1.3-r0 - Ralink 2870/3070/8070/3370/3572/5370/5372/5572 v2.6.1.3 - Development files


root@dm800se:~# opkg list-installed | grep rt5572sta
kernel-module-rt5572sta-3.2-dm800se - 2.6.1.3-r0



This means that kernel-module-rt5572sta-3.2-dm800se - 2.6.1.3-r0 was installed correctly (from feeds) but the Ralink 148f:3070 for me not working (this means that in the setup/net section I can only choose Ethernet, WiFi is not available).

So the drivers of rt5572 are installed but not working for Ralink 148f:3070
