Wireless N300 USB Adapter

"WNA699U8N3.GW64-DL" and "REV1.0" is silkscreened

on the board in the FCC photos.

The FCC test report and labels indicate that this dongle

will also be sold as the...

Per a recent Ralink (MTK) driver set (for a Sitecom MT7610U dongle),

the USB ID for this device is 2001:3c20.

Linux driver

The USB ID for this device was added in linux kernel version 3.13.

The USB ID for this device is not currently in Ralink's driver
or the linux kernel versions below 3.13 (rt2800usb).

Presuming RT5372 support is working, the following commands (executed as root)

should get the device operational, at least temporarily.
modprobe rt2800usb
echo -n "2001 3c20" > /sys/bus/usb/drivers/rt2800usb/new_id

To persist across reboots, the process must be repeated again - you can either

shove commands to readd the USB ID in a script executed upon boot or you will
need to recompile the driver (using backports would be recommended..)

For the vendor driver (rt5370sta), the USB ID will probably need to be manually added

before compilation. The following should be added to common/rtusb_dev_id.c..
{USB_DEVICE(0x2001,0x3C20)}, /* Alpha */

.. in the RT5372 ifdef block.

but has not been further verified aside from that.
