This really looks like a variant of some existing devices, the rt2x00,
Ralink driver.

I've copied the maintainers of that driver here.

Is anyone working on support for the following devices in the existing
rt2x00 USB driver:

        {USB_DEVICE(0x148f, 0x6570)}, /* Ralink 6570 */
        {USB_DEVICE(0x148f, 0x7650)}, /* MT7650 */
        {USB_DEVICE(0x148f, 0x6370)}, /* Ralink 6370 */
        {USB_DEVICE(0x148f, 0x7601)}, /* MT 6370 */

thanks,

Hi,
I'd say I'm midway through with c programming(part of my computer
engineering degree course) and know a decent amount of git. So yes I'm
comfortable writing code.
Also here's the link to an eBay listing for the same hardware.
http://www.ebay.com/itm/like/231051816145?lpid=82&item=231051816145&lgeo=1&vectorid=229466

I think that should do the trick.
Cheers,

Ok great, let's see if it's just a matter of some changes to the
existing kernel driver before we decide to add the whole huge tarball
to the staging tree as fixing it up will be a lot of work.

Thanks, I've ordered a few that look like this, hopefully some will
actually show up.

I believe some people (CC'd) may have been working on / had an
interest in writing such a driver. I'm not sure what the status of
that effort is though.

Right. Felix is working on new linux friendly driver for new Mediatek
chips.

So far i know, Felix is working on abgn+ac (MT7662 and MT7612) devices.
MT7601STA is (a)bgn. Are there similar regs?

In mt7601 code i see parts like "if (IS_RT3290(pAd) || IS_RT65XX(pAd) ||
IS_MT7601(pAd))".  RT3290 is supported by rt2x00.

Well, there is no kernel compatible part in this driver. With other
words it should be completely rewritten or cleaned up. As match as
possible of existing kernel code should be reused.

PS. please keep the topic.

All Mediatek/Ralink devices I know have the same MAC registers, but
different BBP and RF registers.

> In mt7601 code i see parts like "if (IS_RT3290(pAd) || IS_RT65XX(pAd) ||

Hence looks that support for this devices should be added to rt2x00.

Hello everone!
A few months earlier I had requested addition of the MT7601 WiFi
dongle module into the kernel. I was told that the needful would be
done in the rt2x00 driver. Could you guys update me with the status?
Thanks a lot!

FWIW, if this is the mediatek supplied driver (was this
http://www.spinics.net/lists/linux-driver-devel/msg57929.html the
original message?), it has been discussed here before. It works (when
patched[*]) but (IMHO) it's not suitable for kernel inclusion.

[*] I collected those patches plus a couple I made to make it work with
big endian architecture here:
