sorry for the late reply. I switched to the 4.2 image and wifi is now working fine. Just need to fix the no audio issue now;-) Thanks for your help!

Thank you for your interest:-) root@cubieboard2:~# lsmod Module Size Used by rt2800usb 13671 0 rt2800lib 48693 1 rt2800usb rt2x00usb 11033 1 rt2800usb rt2x00lib 41780 3 rt2x00usb,rt2800lib,rt2800usb mac80211 245765 3 rt2x00lib,rt2x00usb,rt2800lib sg 23765 0 cpufreq_userspace 3524 0 snd_usb_audio 99287 0 snd_hwdep 5811 1 snd_usb_audio snd_usbmidi_lib 17859 1 snd_usb_audio snd_seq_midi 4682 0 snd_seq_midi_event 6339 1 snd_seq_midi snd_seq 51584 2 snd_seq_midi_event,snd_seq_midi snd_rawmidi 20567 2 snd_usbmidi_lib,snd_seq_midi snd_seq_device 6371 3 snd_seq,snd_rawmidi,snd_seq_midi 8192cu 454584 0 bnep 14462 2 sunxi_ir 4037 0 hidp 17640 0 rfcomm 58686 0 hci_uart 25000 0 bluetooth 264185 12 bnep,hidp,hci_uart,rfcomm root@cubieboard2:~# lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 006: ID 148f:5572 Ralink Technology, Corp.

Same here. "lshw", "lsusb -t" and dmesg see the device recognized but no driver is applied. Firmware-Ralink package is also installed. Device output from "lsusb" is "Bus 002 Device 005: ID 148f:5572 Ralink Technology, Corp. RT5572 Wireless Adapter". Haven't looked at the kernelconfig yet, could it be a old version of the driver?
