DESCRIPTION

The ural 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).
