NAME
       zyd -- ZyDAS ZD1211/ZD1211B USB IEEE 802.11b/g wireless network driver

SYNOPSIS
       To  compile  this  driver into the kernel, place	the following lines in
       your kernel configuration file:

	     device ehci
	     device uhci
	     device ohci
	     device usb
	     device zyd
	     device wlan
	     device wlan_amrr

       Alternatively, to load the driver as a module at	boot time,  place  the
       following line in loader.conf(5):

	     if_zyd_load="YES"

DESCRIPTION
       The  zyd	 driver	 provides  support for wireless	network	adapters based
       around the ZyDAS	ZD1211 and ZD1211B USB chips.

       zyd supports station and	monitor	mode operation.	 Only one virtual  in-
       terface may be configured at any	time.  For more	information on config-
       uring this device, see ifconfig(8).

EXAMPLES
       The following example configures	zyd0 to	join any BSS network using WEP
       key "0x1deadbeef1", channel 11:

	     ifconfig wlan create wlandev zyd0 channel 11 \
		 wepmode on wepkey 0x1deadbeef1	weptxkey 1 \
		 inet 192.0.2.20/24

       Join an existing	BSS network, my_net:

	     ifconfig wlan create wlandev zyd0 192.0.2.20/24 \
		 ssid my_net

DIAGNOSTICS
       zyd%d:  could not load firmware (error=%d)  An error occurred while at-
       tempting	to upload the firmware to the onboard microcontroller unit.

       zyd%d: could not	send command (error=%s)	 An attempt to send a  command
       to the firmware failed.

       zyd%d:  sorry, radio %s is not supported	yet  Support for the specified
       radio chip is not yet implemented in the	driver.	 The device  will  not
       attach.

       zyd%d:  device  version mismatch: 0x%x (only >= 43.30 supported)	 Early
       revisions of the	ZD1211 chipset are not supported by this driver.   The
       device will not attach.

       zyd%d: device timeout  A	frame dispatched to the	hardware for transmis-
       sion  did  not  complete	 in time.  The driver will reset the hardware.
       This should not happen.

AUTHORS
       The   original	zyd   driver   was   written   by    Florian	Stoehr
       <ich@florian-stoehr.de>,	 Damien	 Bergamini  <damien@openbsd.org>,  and
       Jonathan	Gray <jsg@openbsd.org>.

CAVEATS
       The zyd driver does not support a lot of	the functionality available in
       the hardware.  More work	is required to properly	support	the  IBSS  and
       power management	features.
