After searching through http://openbsd.org/i386.html#hardware and ath(4), I believe I have a currently (as of the latest snapshot) unsupported USB 2.0 802.11b/g adapter, the Airlink 101 Super G, based on the Atheros AR5523. The manufacturer's web site is located at http://www.airlink101.com/products/awll4030.html.
I didn't see a specific request for the device on http://openbsd.org/want.html, but would like to send it to the appropriate developer to see if device support for this chipset can be added to OpenBSD.
