This page details the selection process for Mediatek USB Wifi devices for the ConnectBox.

We will consider chipsets that meet the following criteria:

1. Drivers in the current linux kernel (including the staging tree). We want to avoid building and maintaining drivers
2. 802.11n support (not draft-n)
3. 2T2R (2x2:2) MIMO
4. USB form factor
5. Driver supporting AP (Master mode)

1. Driver support in the current kernel

config RT2500USB
Supported chips: RT2571 & RT2572.
config RT73USB
Supported chips: RT2571W, RT2573 & RT2671.
config RT2800USB
Supported chips: RT2770, RT2870 & RT3070, RT3071 & RT3072
config RT2800USB_RT33XX
Supported chips: RT3370
config RT2800USB_RT35XX
Supported chips: RT3572
config RT2800USB_RT3573
enables support for RT3573 chipset
config RT2800USB_RT53XX
Supported chips: RT5370
config RT2800USB_RT55XX
Supported chips: RT5572

Open question; is RT5372 supported by RT2800USB_RT53XX also?
