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

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  inter-
     face  may	be  configured at any time.  For more information on configuring
     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 192.168.1.1 netmask 255.255.255.0

     Join an existing BSS network, "my_net":

	   ifconfig wlan create wlandev zyd0 192.168.0.2 \
	       netmask 0xffffff00 ssid my_net

DIAGNOSTICS
     zyd%d: could not load firmware (error=%d)	An error occurred while attempt-
     ing 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 ra-
     dio 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 revi-
     sions 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 transmission
     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.
