EnGenius EUB-3701 EXT USB wifi dongle not working

[pigling]

Hi all,
I am using EnGenius EUB-3701 EXT usb wifi dongle in FreeBSD8.0-Release. This is output when I key in "usbconfig -u 7 -a 2 dump_device_desc":

ugen7.2:<802.11 bg WLAN Ralink> at usbus 7, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON
    bLength = 0x0012
    bDescriptorType = 0x001
    bcdUSB = 0x0200
    bDeviceClass = 0x0000
    bDeviceSubClass = 0x0000
    bDeviceProtocol = 0x0000
    bMaxPacketSize0 = 0x0040
    idVendor = 0x1740
    idProduct = 0x3701
    bcdDevice = 0x0001
    iManufacturer = 0x0001 <Ralink>
    iProduct = 0x0002 <802.11 bg WLAN>
    iSerialNumber = 0x0000 <no string>
    bNumCOnfigurations = 0x0001

I think this is a RT73 driver compatible device so I add following line in /boot/loader.conf:

    if_rum_load="YES"

Then I add followings in /sys/dev/usb/usbdevs and /sys/dev/usb/wlan/if_rum.c

in /sys/dev/usb/usbdevs:

vendor ENGENIUS 0x1740 EnGenius
product ENGENIUS EUB3701EXT 0x3701 EUB-3701EXT USB dongle

in /sys/dev/usb/wlan/if_rum.c

{ USB_VP(USB_VENDOR_ENGENIUS, USB_PRODUCT_ENGENIUS_EUB3701EXT) },

After recompiling the kernel, ifconfig command still can't find any wifi device. Has anyone suggestion? Thank.

regards,
qichao

check with "dmesg" command:

dmesg | grep rum

there is some error:

module uhub/rum already exists
module uhub/rum failed to register: 17

So I guess that I have mounted the device twice. I delete the line in /boot/loader.conf:

if_rum_load="YES"

Then reboot, the device can be recognized now.

But still not clear when I should add

if_rum_load="YES"

in loader.conf.

But still not clear when I should add

if_rum_load="YES"

in loader.conf.

When a module has been built into the kernel, it can't be loaded separately. For example, the generic kernel /usr/src/sys/i386/conf/GENERIC includes the rum device:

# USB Wireless
device          rum             # Ralink Technology RT2501USB wireless NICs
device          uath            # Atheros AR5523 wireless NICs
device          ural            # Ralink Technology RT2500USB wireless NICs
device          zyd             # ZyDAS zb1211/zb1211b wireless NICs

If you were to remove or comment out the "device rum" line and rebuild the kernel, then that module would not be included in the kernel. You can load it in /boot/loader.conf or with kldload if_rum.
