26 To compile this driver into the kernel,
27 place the following lines in your
28 kernel configuration file:
29 .Bd -ragged -offset indent
36 .Cd "device wlan_ratectl_onoe"
39 Alternatively, to load the driver as a
40 module at boot time, place the following line in
42 .Bd -literal -offset indent
48 driver supports USB 2.0 and and PCI Express Mini Card wireless adapters based on
49 the Ralink RT2501USB and RT2601USB chipsets.
51 Ralink PCI Express Mini Card adapters show up as normal USB 2.0 devices and
52 are thus handled by the
56 The RT2501USB chipset is the second generation of 802.11a/b/g adapters
58 It consists of two integrated chips,
59 an RT2571W MAC/BBP and an RT2528 or RT5226 radio transceiver.
61 The RT2601USB chipset consists of two integrated chips,
62 an RT2671 MAC/BBP and an RT2527 or RT5225 radio transceiver.
63 This chipset uses the MIMO (multiple-input multiple-output) technology with
64 multiple antennas to extend the operating range of the adapter and to achieve
66 MIMO is the basis of the forthcoming IEEE 802.11n standard.
70 driver supports the following adapters:
92 Cisco-Linksys WUSB54G rev C
94 Conceptronic C54RU ver 2
98 D-Link DWL-G122 rev C1
114 Hercules HWGUSB2-54-LB

148 An error occurred while attempting to upload the microcode to the onboard 8051
149 microcontroller unit.

151 The driver will reset the hardware.
152 This should not happen.
