DESCRIPTION

The driver supports USB 2.0 wireless adapters based on the RT2500USB chipset.

The RT2500USB chipset consists of two integrated chips, a RT2570 MAC/BBP and a radio transceiver (the model of which depends on the card revision).

The RT2522, RT2523, RT2524, RT2525, RT2525e and RT2526 radio transceivers operate in the 2.4GHz band (802.11b/g) whereas the RT5222 is a dual-band radio transceiver that can operate in the 2.4GHz and 5.2GHz bands (802.11a).
