ZYD(4)		       FreeBSD Kernel Interfaces Manual			ZYD(4)

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

     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):


     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).

     The following devices are known to	be supported by	the zyd	driver:

	   Tekram/Siemens USB adapter
	   Telegent TG54USB
	   Trendnet TEW-424UB rev A
	   Trendnet TEW-429UB
	   TwinMOS G240
	   Unicorn WL-54G
	   US Robotics 5423
	   X-Micro XWL-11GUZX
	   Yakumo QuickWLAN USB
	   Zonet ZEW2501
	   ZyXEL ZyAIR G-220

     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	netmask

     Join an existing BSS network, ``my_net'':

	   ifconfig wlan create	wlandev	zyd0 \
	       netmask 0xffffff00 ssid my_net

     zyd%d: could not load firmware (error=%d)	An error occurred while
     attempting	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

     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.

     intro(4), netintro(4), usb(4), wlan(4), wlan_amrr(4), wlan_ccmp(4),
     wlan_tkip(4), wlan_wep(4),	ifconfig(8), wpa_supplicant(8)

     The original zyd driver was written by Florian Stoehr
     <>, Damien Bergamini <>, and
     Jonathan Gray <>.

     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.
