In https://bugzilla.kernel.org/show_bug.cgi?id=114151, the OP reports improved
stability and performance for an RT5370 using a newer firmware that came with
the driver CD. The logs show this to be version 0.36, whereas the version now in
linux-firmware is version 0.29.
I downloaded the firmware from b.k.o. It had very little effect on my no-name
adapter with ID 148f:3070. It still gets ping losses of 10-15%.
Should this new version be submitted to linux-firmware? Its provenance seems to
be sketchy, but submission would likely be legal.

I do not see any reason not to update ralink firmwares in linux-firmware
git tree, however IIRC linux-firmware maintainers prefer to firmware
submission was performed from vendor email addresses.

Version 0.36 can also be found in the vendor tarball on [1] even though it
references a different chip ...
So, in my opinion this should be safe from a legal point of view.

Go to https://bugzilla.kernel.org/show_bug.cgi?id=114151 and copy the attachment
to your ~/Downloads directory. Then do the following:
sudo cp /lib/firmware/rt2870.bin /lib/firmware/rt2870.bin_old
sudo cp ~/Downloads/rt2870.bin /lib/firmware/.
sudo modprobe -rv rt2x00usb
sudo modprobe -v rt2x00usb
If your testing shows a regression in performance, then you can recover by
copying rt2870.bin_old to rt2870.bin in /lib/firmware.

I have an RT5370 adapter from Panda Wireless and use it on my Ubuntu
14.04 laptop.
It is working fine on my laptop.
>From my laptop:
rt2x00lib_request_firmware: Info - Firmware detected - version: 0.29
I didn't see the warnings reported in the Bug 114151.
Just curious how to test version 0.36 on my laptop.
Thanks.
