ZYD(4) FreeBSD Kernel Interfaces Manual ZYD(4)
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
interface 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 192.0.2.20/24
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
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
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
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.
