Read on for a list of devices.

"This current version is commented out in the config files by default but people are welcome to test this code and suggest changes. Only the NetGear MA111 is supported at the current time, however it is possible that several others may work with the USB devices. here is a list of devices which might work according to the linux PRISM2/USB driver.

Thank you, Dale, this sounds quite useful. If you do test this, remember to send in reports of new devices that you can confirm working or any issues you identify. Patches are always welcome.

    Any work being done or interest in the orinoco usb adapters? I have a few of these that I wouldn't mind parting with if there was some real interest in supporting them.

      If they use the same protocol (chipset) as the orinoco pcmcia cards, it should just be a matter of adding the appropriate usb device id. This driver is just a modification of if_wi so that it talks over USB.

        The orinoco/avaya usb adapters actually have an unlabeled orinoco pcmcia card inside. Once removed, the pcmcia card will function just like any other.

    This is great for people with new G4 laptops since the Apple Airport Extreme card is not supported. Now I can have one of these connected when I want to run OpenBSD on the laptop. Which I prefer for longer programming tasks.

      This is exactly the reason it was worked on, a PBG4 12" is not as useful without wireless. And it does not have the option of pcmcia cards.

    Will bridging be possible on these adapters?

    How fast are these devices ? 11Mb/s ? 54 ?

      OpenBSD only supports 802.11b, which while advertised at 11Mbs only pulls about 5Mb/sec half duplex.

        It's not a half/full duplex issue. Wireless is ALWAYS half duplex. The "data rate" is 11Mbps but that inclues an amazing amount of overhead.

          > Wireless is ALWAYS half duplex.

          This is not entirely true. Many wireless applications accomplish full duplex by using two frequencies.

          > The "data rate" is 11Mbps but that inclues an amazing amount of overhead.

          ..and the resulting connection is about 5Mb/sec, half duplex.
