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): if_zyd_load="YES"
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).
The following devices are known to be supported by the zyd driver: 3COM 3CRUSB10075 Acer WLAN-G-US1 Airlink+ AWLL3025 Airlink 101 AWLL3026 AOpen 802.11g WL54 Asus A9T integrated wireless Asus WL-159g Belkin F5D7050 v.4000 Billion BiPAC 3011G Buffalo WLI-U2-KG54L CC&C WL-2203B DrayTek Vigor 550 Edimax EW-7317UG Edimax EW-7317LDG Fiberline Networks WL-43OU iNexQ UR055g Linksys WUSBF54G Longshine LCS-8131G3 MSI US54SE MyTek MWU-201 USB adapter Philips SNU5600 Planet WL-U356 Planex GW-US54GZ Planex GW-US54GZL Planex GW-US54Mini Safecom SWMULZ-5400 Sagem XG 760A Sagem XG 76NA Sandberg Wireless G54 USB Sitecom WL-113 SMC SMCWUSB-G Sweex wireless USB 54 Mbps 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-202 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 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
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.

The original zyd driver was written by Florian Stoehr <firstname.lastname@example.org>, Damien Bergamini <email@example.com>, and Jonathan Gray <firstname.lastname@example.org>.
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.
