Arduino Yun Wifi with Ralink RT5370 and 1.6.2

Hi.

I've tried to install a Ralink RT5370 Wifi dongle (cause I've seen the guides that state that is one of the most compatible and cheapest) and this doesn't seem to work with the latest software version (1.6.2) as it did with the previous one:

With the new version:

# cat /etc/release
DISTRIB_ID='OpenWrtYun'
DISTRIB_RELEASE='1.6.2'
DISTRIB_REVISION='r48749'
DISTRIB_CODENAME='chaoscalmer'
DISTRIB_TARGET='ar71xx/generic'
DISTRIB_DESCRIPTION='OpenWrtYun ChaosCalmer 1.6.2'
DISTRIB_TAINTS='mklibs busybox'

Kernel:

3.18.23

There are NO module packages for this chipset on the default repos:

# opkg install kmod-rt2800-lib kmod-rt2800-usb kmod-rt2x00-lib kmod-rt2x00-usb
Unknown package 'kmod-rt2800-lib'.
Unknown package 'kmod-rt2800-usb'.
Unknown package 'kmod-rt2x00-lib'.
Unknown package 'kmod-rt2x00-usb'.

I've tried to use the openwrt packages for the same...ish version and chipset but, as expected, it doesn't seem to work (unknown symbols)

[ 415.100000] rt2x00lib: Unknown symbol led_classdev_suspend (err 0)
[ 415.110000] rt2x00lib: Unknown symbol led_classdev_resume (err 0)

Is there any way to obtain these module packages/repos or compile my own ones?, I really don't have a clue where I should start searching.

Thanks in advance.

Regards.
