this driver into the kernel, 27place the following lines in your 28kernel configuration file: 29.Bd -ragged -offset indent 30.Cd "device ehci" 31.Cd "device uhci" 32.Cd "device ohci" 33.Cd "device usb" 34.Cd "device rum" 35.Cd "device wlan" 36.Cd "device wlan_amrr" 37.Ed 38.Pp 39Alternatively, to load the driver as a 40module at boot time, place the following line in 41.Xr loader.conf 5 : 42.Bd -literal -offset indent 43if_rum_load="YES" 44.Ed 45.Sh DESCRIPTION 46The 47.Nm 48driver supports USB 2.0 and PCI Express Mini Card wireless adapters 49based on the Ralink RT2501USB and RT2601USB chipsets. 50.Pp 51Ralink PCI Express Mini Card adapters show up as normal USB 2.0 52devices and are thus handled by the 53.Nm 54driver. 55.Pp 56The RT2501USB chipset is the second generation of 802.11a/b/g adapters from 57Ralink. 58It consists of two integrated chips, an RT2571W MAC/BBP and an RT2528 or 59RT5226 radio transceiver. 60.Pp 61The RT2601USB chipset consists of two integrated chips, an RT2671 62MAC/BBP and an RT2527 or RT5225 radio transceiver. 63This chipset uses the MIMO (multiple-input multiple-output) technology 64with multiple antennas to extend the operating range of the adapter 65and to achieve higher throughput. 66.Pp 67.Nm 68supports 69.Cm station , 70.Cm adhoc , 71.Cm hostap , 72and 73.Cm monitor 74mode operation. 75Only one virtual interface may be configured at any time. 76For more information on configuring this device, see 77.Xr ifconfig 8 . 78.Sh HARDWARE 79The 80.Nm 81driver supports USB 2.0 wireless 82adapters based on the Ralink RT2501USB and
