Found another Ralink device that works: RT5370. Used exactly same instructions given by Anna (same .bin files). There seems to be a lot of low cost dongles based on this device. This was a "BG/N" from ebay for $5.
This was a USB dongle replacement for failed wireless on early XO-1.5 (static discharge damage ?). Removed (unplugged) failed internal wireless. Linux drivers RT2800usb in kernels 3.0.0-12 (?) or later. This XO-1.5 had 13.2.0 installed, but should apply to 12.1.0 . Worked with second XO-1.5 (which had 11.3.0 installed) running Chat Activity.
Also works on XO-1 (internal wireless intact) with 13.2.0 .
Initially, I was distracted with info from google search about changing device id in udev.rules - proved unnecessary. The dongle is assigned to wlan0 .
Now, is there a device based on Ralink chips to replace the internal Libertas wireless module ? :)
Finally, will this XO-1.5 now function as an XSCE server (i.e, will wlan0 get properly reassigned to eth0).
Using udev reassignment (persistent-net.rules) method used on 11.3.0's (2.?.? kernel) does not seem available on 13.2.0 .

Just like the Atheros dongle, to get it to work on the XO-1 was just a
matter of finding and downloading the firmware for it, then putting the
firmware into /lib/firmware.
I'm on yet another XO-1 with a dead internal wifi chip, all that shows up
natively is loopback.
Here's the lsusb output for the dongle:
Bus 001 Device 004: ID 148f:3070 Ralink Technology, Corp. RT2870/RT3070
Wireless Adapter
Google quickly pointed me here:
I cloned the firmware repo:
git clone git://
git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
Poked around in the linux-firmware dir and found rt2870.bin and
rt3070.bin. Cp'd those two files to /lib/firmware on the XO-1, inserted
the dongle, then checked out Network Neighborhood. Yep, saw AP circles.
Powered up the other XO-1 with "broken" wifi I was playing with last night,
the one with the Atheros dongle. Yep, the buddy icons show up in Network
Neighborhood (since both devices are on the same LAN). Tested the chat
activity just to be completely sure Sugar collaboration over the LAN works
with dongles.
