Basically there are three options for USB to 802.11 adapters. Option 1. USB to PCMCIA adapter, with a PCMCIA card (almost always a Prism II family device) plugged into it. Used by Agere Systems Orinoco USB Client, and by Compaq (WL215 seems to be same device). No current support in Linux (and no-one actively working it AFAIK, although a few people have asked for support). The best way to do this would be to make a USB to PCMCIA bridge driver (a peer with yenta socket, for example), and then use the orinoco driver that Dave Gibson maintains in the kernel. The USB to PCMCIA adapter is known to be based on a Cypress EZ-USB (maybe FX?) device that probably needs firmware downloads. Supporting this device would need access to the specs on the USB protocol used by the firmware. I asked Cypress for the specs, they said it wasn't their design. Option 2. USB interface to the existing Prism II (and II.5) MAC. No commercially available device is known to use this. There is a Linux driver (ftp://ftp.linux-wlan.org/pub/linux-wlan-ng/linux-wlan-ng-0.1.11-usbonly.tar.gz) - I haven't looked at it. Option 3. USB interface to the Atmel AT76C503A MAC. Used by Dlink (DWL-120) and Linksys (not the same design). Open source Linux driver in work, currently only the firmware download works (from userspace), and some simple status reporting, although I am planning to work on it in the next month. There is a binary driver being developed by Atmel, although I haven't tried it yet.
