Ralink RT2573 driver not working


I am using the last LEDE release (17.01.2) with my raspberry pi 3.
I attach a wireless USB dongle I have, I see it when running lsmod:
Bus 001 Device 004: ID 148f:2573 Ralink Technology, Corp. RT2501/RT2573 Wireless Adapter

But when I run this:
opkg update
opkg install rt73-usb-firmware
and reboot, I check with:
dmesg, ip link show and iw list but I don't see the device.

By the way, the interesting thing is that the dongle works without installing anything when using the last version raspbian.

Any help or suggestion?
Thanks a lot.
