>Description:
Belkin F5D7050 is a usb device with 802.11g capability and is referenced
in the FreeBSD hardware notes as an acceptable wireless device which uses
the zyd device driver.

dmesg shows:

zyd0: <Belkin USB2.0 WLAN, rev 2.00/48.10, addr 2> on usbus2

upon insertion, device is recognized as zyd0

"ifconfig wlan0 create wlandev zyd0" creates wlan0 as expected

"ifconfig wlan0 up scan" causes system to immediately reboot. no panic
message seen. no entry in /var/log/messages.
>How-To-Repeat:
1. plug in Belkin F5D7050
2. ifconfig wlan0 create wlandev zyd0
3. ifconfig wlan0 up scan
